It started when I was writing Design for Hackers 10 years ago. Couldn’t figure out why nothing I had learned about productivity had prepared me for writing a book.

The gist:

- People say “there’s only 24 hours in a day” as if you need to make use of those hours. What it really means is “time management” is like squeezing blood from a stone.

- We’re entering the Creative Age. You have to be creative to stay relevant in the robot apocalypse.

- We know from the work of neuroscientists John Konious and Mark Beeman that insightful thinking is unique. It’s promoted by a relaxed mood. It’s a fragile state: Hard to get into, easy to ruin.

- We each have “peak” and “off-peak” times of day. Counterintuitively it’s the off-peak times when you’re more creative. (If you’re groggy in the morning don’t ruin it with a cup of coffee).

- There are four stages to creativity: Preparation, Incubation, Illumination, Verification. Respect these stages and you won’t get blocked.

- You can work with natural cycles in the day, week, month, or year to go through the four stages. For example, you can use a night’s sleep as Incubation.

- Organize your tasks not by project but by mental state. I’ve identified seven mental states by which I organize my tasks: Prioritize, Explore, Research, Generate, Polish, Administrate, Recharge. (I personally prefer Todoist’s “labels” feature).

- Not all hours are equal. When I was working with behavioral scientist Dan Ariely on Timeful, we noticed there aren’t 24 hours in the day – there’s an hour here or there for various mental states.

- By harnessing cycles and working according to mental state, you can build systems that account for Incubation. For my podcast, tasks that used to be 1 grueling hour are now spaced into three five-minute bursts, with space for Incubation.

- In a chaotic world, you want your creative systems to be antifragile. Leave slack for chaos, and be ready to capture the opportunities chaos presents, for breakthrough ideas.
