Energy & Rhythm

Your capacity isn't constant through the day, and treating it as constant is why the afternoon feels like wading. These tools fit work to rhythm. Find your peak window and defend it for the work that needs it. Use the 90-minute block the body actually runs on. Watch for decision fatigue before it degrades the calls you make late. Time-box instead of time-block when the task is open-ended. Same hours, much more output — because the hard work lands when you can do it.

Work Your Peak Window 3 min

Best hours for best work. Everything else gets the scraps.

You're spending your sharpest hours on meetings, email, and reactive tasks.

Ride the 90-Minute Wave 2 min

Ninety minutes on, then a real break. Ride the rhythm.

You have a block of 2+ hours and need sustained, high-quality cognitive output.

Check Your Decision Tank 2 min

Important decisions deserve a full tank, not the fumes.

A significant decision lands late in the day, after hours of meetings, or when you feel mentally flat.

Stop Before You're Done 2 min

Stop mid-flow so tomorrow starts with momentum.

You're ending a focused work session and will return to the same project tomorrow.

Box the Time, Don't Block It 2 min

This gets 45 minutes, not a moment more. Go.

You're prone to perfectionism, scope creep, or spending far longer on tasks than they deserve.
