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.

I have a very peculiar answer. Really, really amazing nail clippers. Pay 50 bucks for them, or something. It could change your life, I promise.

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.

So, I recently bought the FINIS, F-I-N-I-S, swim paddles. They somewhat magically lengthen out my freestyle stroke. And when I combined them with some fins, I use the ones Cressi, C-R-E-S-S-I, I feel sometimes like I’m almost flying through the water.

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.
