When

Three of the ideas you’ll keep

The Clif summary of When pulls out 8 insights. Here are the first three.

1. Map your day into Peak, Trough, and Recovery, then match tasks to each: do analytical, high-focus work at your Peak, dump routine admin into the Trough, and save brainstorming and creative work for the Recovery.
2. Find your chronotype. Lark, Owl, or Third Bird, because it sets the *order* of your stages; owls should flip the schedule and tackle hard analysis in the late afternoon/evening, not the morning.
3. Treat breaks as a performance tool, not a weakness: short breaks that get you moving, outside, social, and fully detached from screens restore focus far better than powering through.

The other 5 — and the full 10-minute summary — are in the app.
