Energy is a cycle, not a flat line

Trying to maintain constant high focus through willpower is a losing game. Your energy naturally rises and falls in roughly 90-minute cycles through the day. Working with those rhythms, rather than against them, gets far more done with far less strain.

Manage your energy

• Do demanding, focused work during your natural high-energy windows.
• Schedule routine or low-stakes tasks for your predictable dips.
• Take real breaks between focus blocks — energy recovers in the pauses.
• Protect the basics — sleep, food, movement — that set your baseline energy.

Notice your own pattern: many people peak late morning and dip mid-afternoon. Once you know yours, you can design your day around it instead of fighting it. Managing energy well beats grinding on willpower — and it’s far more sustainable over months and years.
