We have, as human beings, a storytelling problem. We're a bit too quick to come up with explanations for things we don't really have an explanation for.

Economists often talk about the 80/20 Principle, which is the idea that in any situation roughly 80 percent of the “work” will be done by 20 percent of the participants. In most societies, 20 percent of criminals commit 80 percent of crimes. Twenty percent of motorists cause 80 percent of all accidents. Twenty percent of beer drinkers drink 80 percent of all beer. When it comes to epidemics, though, this disproportionality becomes even more extreme: a tiny percentage of people do the majority of the work.

If you look at the careers of great entrepreneurs and you look at the moment they took their plunge, the plunge is rarely a great financial or material risk, it’s a social risk. At the moment they started their new businesses, everyone around them said ‘you’re an idiot’.

When you're an underdog, you're forced to try things you would never otherwise have attempted.

Jenny Simpson loses her shoe in the women's fifteen hundred, with a lap and a half to go, destroying her chances to repeat as world champion, and she gives the most gracious interview afterward about how she's had a wonderful career already. Great for Jenny Simpson. Bad for the sport! We need drama!

My highest compliment is when someone comes up to me to say, "My 14-year-old daughter, or my 12-year-old son read your book and loved it." I cannot conceive of a greater compliment than that - to write something that as an adult I find satisfying, but also that manages to reach a curious 13- or 14-year-old.
