Good question. I’ve heard you ask this before, and I didn’t think you were going to ask me, and I should have been prepared for this. I’m a huge, avid reader. I truly believe – and I tell every person I train – is that one of the biggest reasons – the difference between where you are and where you want to go is knowledge. Read as much as you can. So, that’s a tough question. I think The Alchemist is a big one. I’ve loved that book for a very long time. The Bible is a big one, but I’ll give you an off-the-wall one, which is called The Slight Edge . Have you ever heard of that one?

Yeah, totally. Of course now, all my friends are having kids. I give kids books, but the one I give people that are trying to learn actively is Principles by Ray Dalio. It’s interesting actually. Someone gave me the PDF. It was a PDF before his book. Gave me the PDF and I skimmed over. I was like, “Oh, this is pretty good.” They were like, “No. I seriously think you’re going to love this.” For some reason, I didn’t get around to it for maybe a year-and-a-half, and then I read the actual book, and I was blown away. It’s both a guide to life, a guide to business, and also I think an insight into Ray and someone who’s built an amazing business. If you guys listening don’t know what he does, he runs a hedge fund called Bridgewater and he’s so much more than just a finance thinker, he’s also just a brilliant philosopher. I give that a lot because I think it’s a great guide to life.

I think the one that has had the biggest impact on me and the one that I’ve given the most number of people has been [The Better Angels of Our Nature] . And [The Better Angels of Our Nature] is a 700-page book on death. And it’s written by a brilliant Harvard professor who talks at great length about death rates and the human condition. And he spends a lot of time talking about what happened 200, 300, 400, 500 years ago. And when you finish the book, which takes a long time, you conclude that the world is in a much, much better place than it has been in the past, that a thousand years ago, the average man died in a war and the average woman died in pregnancy in their 20s, and that a child born today has a very high likelihood in almost all parts of the world to live to a natural old age. That’s an extraordinary statement. And that’s why the people who run around saying, “Oh, the world’s falling apart. We’ve never had it this bad.” That’s just not true. And the data says it’s not true.

In Ge Hong's A Handbook of Prescriptions for Emergencies (肘后备急方), I noticed one sentence "A handful of Qinghao immersed in two liters of water, wring out the juice and drink it all" (青蒿一握, 以水二升渍, 绞取汁, 尽服之) when Qinghao was mentioned for alleviating malaria fevers. Most herbs were typically boiled in water and made into a decoction before taken by the patients. This unique way of using Qinghao gave me the idea that heating during extraction might have destroyed the active components and the high temperature might need to be avoided in order to preserve the herb's activity.

I’ve been told that because I like to make up silly songs and then sing them in all sorts of absurd situations and occurrences, that I am trying to turn my life into a Hollywood musical. Since I was first told that, I’ve come to completely agree with that, and I think that is awesome. But I have songs for everything.

one of the things that I learned from doing Design Matters from my guest Danny Shapiro, and I think I mentioned this in part one of my interview with Tim; confidence is overrated. Danny Shapiro has said that what is more important than confidence is courage.

Well, the purchase that has influenced me over the last six months is the Apple pencil. I do so much of my artwork by hand and now there is a device that draws and feels like a real pencil that I can use electronically. It’s changed the way I work.
