I hate to plug my other podcast, but on episode two I went out and interviewed this guy that is a master of pens. He knows more about pens than we do about anything else on earth. He recommended three pens that have the absolute best rollerball pen, the best fountain pen – and these are all $4.00 pens. ... I swapped out my entire stock of pens at my desk with these cheap little $3.00 to $4.00 pens and they’re amazing.

Actually, this is quite random, but I love it. It’s a diffuser for aromatherapy oils. My piano is in my lounge and I have this diffuser on. I put different oils in. For when I’m practicing, I would put geranium in, for instance, which I love. I just find it relaxes me, but at the same time keeps me perked up enough to be able to work.

That’s a great question. Coconut oil. ... Everything. You can take a bath with it. You can put it in a smoothie. You can cook vegetables with it. You can actually put it on your skin. I think coconut oil is a cheap miracle buy.

As a child, it was a yo-yo because I never could master the yo-yo, and it would drive me crazy. And the fact that I couldn’t master it drove me crazy.

Yes. There are three books that I’ll mention. The first one that I’ve gifted the most is called Complexity by Mitchell Waldrop, which is about the rise of the Santa Fe Institute. Even when you were talking with Haidt, I think he mentioned certain things are complex adaptive systems. They’re very hard to predict, they’re very hard to analyze, they’re very hard to understand. That’s what Santa Fe’s all about. That book introduced me to network effects. When I get to go there, I usually go a couple times a year and Mike Mauboussin’s there and Josh Wolfe’s there from Lockton. I just love the learning of things I don’t know, and just pushing my brain to go farther than I would with the normal stuff I consume. It’s beautifully written. Great writer, Mr. Waldrop. There’s a book that I happen to have right here. This book, Mr. China is fantastic. He went to China in the mid ’90s and started a fund to privatize a bunch of industries. He’s from London and got his head handed to him and survived enough to write a humorous story about it. But holy shit.
