How do I practice energy management?

The most direct way to practice energy management is through a focused exercise: For five consecutive workdays, rate your mental energy at four fixed times: 9 AM, 12 PM, 3 PM, and 7 PM. Use a simple 1-5 scale (1 = foggy/depleted, 5 = sharp/focused). At each checkpoint, also note what you're doing, what you ate last, and how much sleep you got the night before. At the end of the week, plot the numbers. You'll see a shape — your energy signature. Most people discover their peak and trough fall within the same two-hour windows every day.

Common pitfall: Knowing your energy pattern intellectually but continuing to schedule high-demand work during your trough because of calendar pressure or guilt. The knowledge becomes performative — you can explain chronotypes at a dinner party but still burn your best hours on email. The gap between mapping your energy and actually reorganizing your day around it is where most people stall.

This practice connects to Phase 6 (Pattern Recognition) — building it as a repeatable habit compounds over time.
