In How to Build a Billion Dollar App George Berkowski takes you through the stages of coming up with a mobile app from concept to being a billion pound company. It is based on his story co-founding taxi app Hailo.

As you might expect it is a pretty whistle-stop tour of each stage of the business. However, it provides a good overview with various comments and advice that Berkowski brings from his experience at Hailo. He stresses the importance of getting the product right for the market and how you should be measuring growth, two of the keys to getting a successful product out there.

While it is a good overview, I am not sure how much I am going to take away from it. Compared to something like The Hard Thing About Hard Things which offers plenty of specific and useful advice, this is more of a general guide to the journey. The one thing I did really like was a list of concepts that have universal appeal to humans. This is great for brainstorming ideas from.

I also found it interesting that he recommended having one Scrum Master for around 12-15 engineers. I have worked at a number of companies that do agile and a typical setup in the UK would be one Scrum Master to around 3-5 engineers, a considerably different ratio.

We don’t often repeat recipes in the Worfolk household. There are so many amazing cuisines, cookbooks and ideas out there that we try something new almost every night. However, there are some recipes that are tasty enough, quick enough or reliable enough that they are reused on a semi-regular basis.

As you might imagine from knowing me, I keep them on a spreadsheet. I thought it would be interesting to analysis how many recipes from each cookbook made it onto the spreadsheet and therefore which cookbooks have stood the test of time.

I have linked through to the review, where one exists.

* indicates I am still working my way through this book.

This isn’t an exact science. I re-use some recipes more than others. If anything, Veg Every Day deserves to be higher because I use that a lot, whereas although I have marked Easy One Pot as having a recipe I would re-use, I certainly don’t go for it anywhere near as much.

It is also unfair on some of the books. A lot of the baking books for example are full of amazing recipes that I have yet to try, but one might day and find they are definitely keepers.

Based on these figures, it seems sensible for me to recommend River Cottage and Mary Berry cookbooks. River Cottage consistently does well. The original River Cottage Cookbook isn’t really a cookbook, it’s more of a book about self-sufficiency, so it is not surprisingly it did not do well. The River Cottage Fish Book did not score so well either, but it was fun read. At the other end of the table, both of my favourite River Cottage cookbooks are storming ahead.

Mary Berry is also on the recommendation list because I am working through my second cookbook of hers at the moment and that is also going to score well. Plus they’e excellent for easy meals and dinner parties as they almost always contain instructions for making in advance.

UPDATE: Since writing this, I have finished working my way through Mary Berry Cooks that added 8 new recipes onto my spreadsheet. That puts it in third place behind the two River Cottage books.

TED Talks: The Official TED Guide to Public Speaking is a book by Chris Anderson, curator of TED, on how to deliver a great talk. It is aimed to give advice to everyone, not just people speaking at TED, and while all the examples are from TED, there is much to be learned from anyone looking to give a speech.

As with a great TED talk, Anderson starts the book by creating a vision. An idea is a thought pattern in your head, and your challenge is to replicate that thought pattern inside the mind of each of your audience members. He then goes on to explain how to do this, step by step.

Most of the book concentrates on the idea of getting your message correct. This makes sense because it is more important than delivery and you can do in written form. If your body language or voice is not perfect, this matters less than having a great message. Nor can you teach these skills effectively in a book.

There are also discussions of the fine lines you run into when speaking. Sharing personal stories for example. Generally speakers don’t do enough of this. Showing an audience your vulnerabilities and being open about some of the challenges you have faced really helps you connect with an audience. But you can overshare and even make them feel uncomfortable if you go too far.

Similarly, how much should you rehearse. Should you do it word-for-word or just rehearse ideas? Word-for-words means you will know it better and get it right: but it can also sound forced and unnatural. Both approaches can work. However, in general word-for-word is better. Many speakers, usually with high opinions of themselves, will talk about how they just blag it and it comes out brilliantly. For a tiny proportion of speakers this may be true. However, for most they simply do not sound as good as they think they do. In comparison, I am often complement for how natural and unrehearsed I sound. The speeches that people usually make those comments are the ones I have rehearsed to death: my guess is that that style only comes from the confidence of knowing your speech inside out.

I was quite pleased when the book suggested you should use blank slides to bring the audience back to you. I use this in my speeches, but I have never seen or heard anyone else suggest it before, so it was nice to see TED recommends it too.

One interesting point of contention was the pace you should speak at. At Toastmasters, we always tell people to slow down. TED says the opposite. People can digest faster than you can physically say things, so why would you slow down for anything other than the complicated bits that cause a high cognitive load on your audience? I see their point. If your audience can comprehend you speaking at normal conversation speed, why not pack in more information?

I think both these points of view can be reconciled. A Toastmasters, we’re typically teaching nervous speakers to get over their fears. When people are anxious they speak faster. Slowing down is a skill you need to learn and practice because otherwise you will go a million miles per hour. However, once you have learned to go at your own paces, to add pauses in the right places and to speed up and slow down as required, then you can use that skill to speed up as appropriate.

More choice is always better, right? Not according to Barry Schwartz, author of The Paradox of Choice. In his book, he argues that more choices actually make us less happy.

He begins by talking about buying a pair of jeans. He went into a shop and asked for some. The shop assistant asked him a lot of questions: what colour, what fit, what treatment, what distressing, and what type of fly did he want. His answer: “I want the kind that used to be the only kind.” Not only did he now have to make a decision, which takes cognitive effort if you want to make the right decision, but the increased choice raises our expectations that we will get something better.

This is something I strongly identify with. When I need some new trainers I walk into a shoe shop and look at the choices. If you head down to Sports Direct in Leeds you will find literally a thousand shoes on the wall (I might be over-estimating, but not by much: it’s huge!). Does that make it easier to find the shoes I want? No! It makes it harder. Much harder. I spend time searching for the perfect shoe. If there were just six choices my life would be so much easier.

All of this choice might be okay if we made good decisions and were happier for it. But neither of these are true. Humans are terrible at making rational decisions and Schwartz summaries a lot of Thinking, Fast and Slow as well as other research to prove it. Anchoring is a big one, but there are many. Sunk cost fallacy is another big one: why continue to eat when you are uncomfortably full? I do that all of the time.

He goes on to say that people fear regret and try to avoid it. Therefore people often opt for reversal decisions: buying items you can return, booking things you can cancel for free, etc. However, the research shows that this makes us less happy because we continue to meditate on the choice after having made it. Whereas, if it is reversible we just get on with it. This affects small decisions, like ordering food from a restaurant menu, to life-changing decisions like marriage.

How does Schwartz recommend we remedy this? He has a number of suggestions. The most important is be a satisficer, not a maximiser. A satisficer wants something that is “good enough”. A maximiser will spend as much time as possible making the perfect decision. You could spend a month of weekends travelling around stores to find the perfect coffee table. Or you could buy the first one that would look good enough in your house. Which option do you think will make you the happiest?

It’s option B by a long way. Option A not only wastes all of your weekends, but you will regret all the possible coffee tables you did not buy, and the happiness of finding the best one will wear off over time. Which brings me onto another one of his suggestions: be aware that your happiness is making a good decision will wear off over time. If you expect it, it is not as bad.

Finally, consider artificially limiting your choices sometimes. Do you know one of those people who always choose the same thing when you go to a restaurant? They’re usually really happy with their food. Instead of considering twenty different locations to visit on holiday, consider two or three. Make a non-refundable booking so you don’t get tempted to change your mind and you will enjoy it more.

It is also worth noting that not everyone agrees with Schwartz. I wrote about this last month in a blog post about Schwartz’s TED talk on the same topic.

A Man’s Guide to Having a Baby is a book on parenting by Dominic Bliss. I picked up the hardback edition. It’s a short book and you can knock through the entire thing in an hour or so if you’re not religiously re-reading everything. I have read a few books already, so I was pretty relaxed about it.

It is straight forward as to what it offers. It is for men and makes no bones about it. It strikes me as a book that is more useful than most out there. There are diagrams on how to do things. That is far more useful than the books that say “you’ll pick it up” or talk you through it in general terms. There is even a short troubleshooting guide for common problems and how to fix them.

Selfish Reasons to Have More Kids is a book by economics professor Bryan Caplan and has quickly become my favourite book on parenting. In it he argues that regardless of the number of kids you were going to have, a few more might be better. So if you were planning on zero, maybe you should have one. Or if you are planning on having four, maybe you should have six.

His thesis is that having children is actually less work than most parents put themselves through. People spend hours and hours ferrying their children round activities and after-school clubs, playing them Mozart and generally doing things they hate doing, and often the child hates doing, because they want the child to be more successful.

However, all the research shows that this has basically no effect. Whether it is IQ, happiness, success, character or honesty, most of it is set by genes and the rest is set by the environment, only of which a small fraction is parenting. Therefore parents are simply making themselves totally unhappy for basically no gain.

Let’s say you have a child, and the chance of them growing up to be a lovely person is 80%. You could work really hard and sacrifice your life to budge that to 82%. That gives you an 82% chance of having a lovely child when they’re grown up. Or, you could do nothing, have two kids, and give yourself a 96% of having at least one lovely grown-up child.

Even religion is not determined that much by parenting. What parenting does affect is the labels that people use. But actually turning up to the place of worship as an adult is a whole different ball game.

They are drawbacks to having more children. However, Caplin tackles these too. For example, people without children are slightly happier than people with children. Repeated studies find this. However, when you take out all the stuff the parents hate doing, this gap is incredibly small. Also almost no parent says they regret having kids, whereas the majority of childless people do say they regret it. Finally, most of the happiness hit is with the first child, so once you have had one, you might as well keep going.

There is also the time, money and sleep loss. Caplin tackles this too. This is a short term perspective. Sure, four kids is a huge amount of kids if they are all three years old. But, by the time they are teenagers you will probably have to ask them to spend time with you. And by the time they are adults it is a pleasure to have four adult kids that you can go see. Not to mention that the only reliable way of improving your odds of grandchildren is to have more children yourself.

Is it a message of doom and gloom that parenting doesn’t matter? Not at all. You can change your child in the short term. Discipline, for example, is necessary to have any kind of sane household. Just don’t expect those lessons to last forever. More importantly, the one thing you do have a long-lasting impact on is how your child remembers and perceives you. So shower them with love and kindness. Don’t bother doing stuff you both hate, or culture-cramming. Instead, use your time together to just have fun. It does no harm and makes both of your lives more enjoyable.

Zen and the Art of Motorcycle Maintenance is a book by Robert M. Pirsig. It tells the story of a motorbike trip across America that he and his son Chris undertook. It reads like a novel, and in fact I thought I was reading a fictional story for most of it. However, it is actually an autobiographical retelling.

Pirsig uses the rides to go into deep philosophical discussions he labells as “chautauqua”. These explore the meaning of the term quality and slowly retell his life story: he explored the concept as an academic, to such a degree that eventually led him to a breakdown.

I found the novel dragged quite a bit. I am simply not that interested in epistemology in its relation to quality. It is interesting to hear his life story, but I think you have to have a strong interest in philosophy to enjoy the novel to its full extent.

I read The Wind in the Willows many times as a child. It is a lovely story so while looking for a low cognitive load and pleasant read, it seemed like an excellent choice. It was. It is such a fun story and moves at a pace that it is difficult to get bored. There was none of the usual awkward drag I find plagues most novels at least once. This is despite, or possibly in part because, I knew what was coming next.

Expecting Better: Why the Conventional Pregnancy Wisdom is Wrong and What You Really Need to Know is a book on pregnancy by economist Emily Oster. Oster is known for applying her economics to other fields having given a TED talk on re-thinking AIDs in Africa. During the pregnancy of her first child she got sick of uncited recommendations and decided to look at what the evidence really said.

Take alcohol for example. I wrote about alcohol and pregnancy last month. Oster’s review of the available evidence and theory behind alcohol use during pregnancy is that having up to one drink per day is fine after the first three months. Coffee gets the green light too.

There is no evidence that bed rest is beneficial for pregnant women. In fact, it is quite the opposite: laying around for weeks or even months on end is likely to have a negative impact on the mother’s health. Aromatherapy provides no benefit either, but not everything is out the door: having a doula at the birth produces much better health outcomes.

With each topic, each stage of the pregnancy and each taboo, Oster reviews the available evidence and produces a short summary at the end of each chapter explaining what is safe and what is not. This is by far the most important book on pregnancy I have read.

How important is face-to-face contact? In her book The Village Effect, Susan Pinker argues it is super important. In almost every key aspect of our lives, strong social ties play a large role.

Longevity for one. Pinker shows that strong social ties have one of the strongest effects on life expectancy, bigger than almost any other factor. She discusses the villages of Sardinia where a strong sense of family and relationships help record numbers of people reach the age of 100. Interestingly, these stronger social ties not only help people live longer but also reduce the gender gap.

The differences in social ties can also explain other differences between gender. Men tend to have a wider less-intimate social network while women have fewer but closer friends. On average this benefits men more in things like the workplace as high-paid jobs are often gained through a weak connection. However, in terms of longevity it gives women the advantage because they have more people to confide men. Men on the other hand often only have one person, their spouse, and therefore nobody should their spouse die.

Having plenty of social relationships is important then, but it also turns out that they need to be face-to-face. Otherwise, no oxytocin release for you. Unfortunately spending time socialising online actually reduces face-to-face contact. The number of personal emails somebody sends directly correlates with depression.

Strengthening your intimate social connections has a large benefit. For example, getting married. I assumed that cohabiting was just as good as getting married. It’s not. People who choose to get married (marrying for family pressure does not count) live longer than unmarried people. Being in a marriage reduces your chance of cancer, depression, hospitalisation, premature death and prison.

In the workplace, increased social connections can bring benefits too. Call centres used to schedule people’s breaks at different times. What happened when they aligned people’s breaks so they had 15 minutes to chat to each other? Productivity and team work went up by a significant amount. In contrast, remote working has a negative effect on integration and cohesiveness.

Pinker suggests that being loneliness is a lot like being hungry. It causes you to feel actual pain. This is because we evolved in a world where we needed to stick together. Being excluded from the clan was a death sentence. So, just as being hunger-pain is a sign you need to get some food, loneliness-pain is a sign you are in danger of losing the group. We fear exclusion and people talking behind our back because we are tuned by evolution to fear exclusion.

What message should we take away? That social connections are really important If you want to live a long and happy life (and surely all of us want at least one of those) then having strong social connections is key. Spend time with people, and make sure that time is spent face-to-face.

P.S. If you are wondering if Susan is any relation to Steven Pinker, the answer is yes, they’re siblings. Anything that comes out of the Pinker family seems to be an amazing read.
