I think a lot of them will probably be in the cooking space. Definitely On Food and Cooking . I’ve gifted that a lot. My career starts with that book in many ways. There wouldn’t be any of this modern cooking movement without Harold’s book, I don’t think. There certainly wouldn’t be modernist cuisine that played a big role in my career without that book. So I’ve gifted that a lot because I think it’s relevant and I think for a certain type of individual, it’s the kind of book that every time you open it up, you see something. You’re like, “I didn’t even know that was there; that’s super cool.” And you read something and go, “The world is way more interesting than I thought.” I think I’ve gifted Michel Bras’s Essential Cuisine quite a bit, although it’s hard to do now because I think it’s out of print in English and quite expensive. The other book I found myself gifting a lot lately is an out-of-print book on thermodynamics called The Second Law . It was written by an Oxford physical chemistry professor named P.W. Atkins. That book is just a phenomenal, casual, infographic-laden read on how the world works from an energy perspective. I found that so incredibly useful in trying to understand how to do something, how to make something work, whether something’s even possible. It’s frequently my bullshit detector. When somebody’s trying to convince me some technology or some idea has merit, I very quickly come back to just sketching out the kind of thing I did for that email, where it’s like, let me just see – with knowing nothing about the subject, if I can just sketch out the basic ideas of how much energy is going to be involved or consumed or if I assume limitless capacities, does this make any sense ever? So many things sound good, but just don’t pass muster as soon as you start looking at the world that way. You’re like, “Well, that’s clearly just a waste of everybody’s time and we should just stop and go do this thing over here,” which at least you’re not having to invent new physics or violate the laws of physics to go do it.

Well, other than Man’s Search For Meaning , which is probably my number one gift, recently, the last couple years there’s a book called The 100-Year Life . The 100-Year Life , written by a couple Brits, and it sort of says, “Imagine the future where the average person lives to 100. How is that going to change on a personal and societal basis?” It’s a really interesting, observational book. The Happiness Curve , which we talked about earlier. The U-curve of happiness is what we call it. The name of the book is by Jonathan Rauch, it’s called The Happiness Curve . That’s become a favorite to gift. I also love Danny Meyer the restaurateur. He’s got one of the best books on hospitality ever written, which is called Setting the Table .

Oh, what a great question. I actually gifted one recently. So a friend of mine, Ian Dawson, he trains mountain rescue people, mountain rescuers in Scotland. He was working with me at the North Pole and he’d never seen a polar bear before. He absolutely fell in love with the environment and I gifted him a book called Arctic Dreams by Barry Lopez. Have you read that? Tim Ferriss: This is on my to-read list, Of Wolves And Men by Barry Lopez is one of my favorite nonfiction books I’ve read in the last 10 years. Sue Flood: Oh, it would be. Tim Ferriss: And Arctic Dreams , I was just saying on the way here in the airplane that I wished I had Arctic Dreams , so I haven’t read it yet. Sue Flood: It is a magical book and yeah, I gifted that to Ian and I know he loved it and yeah, that is a great read. You have to immediately dash off, well perhaps not now, but when you get back to civilization. Yeah, that’s a really beautiful book and I’ve bought that for quite a few people.

Over the years, I have found a few resources for developing personal productivity that I love. My top picks include Getting Things Done by David Allen, the classic The 7 Habits of Highly Effective People by Stephen R. Covey, and Learning How to Learn Barbara Oakley (I recommend the Coursera course). I'm tempted to add Tiny Habits to this list.
