How to plan around variable energy, not your ideal self

Plans fail when they assume every day has the same capacity. Instead of asking what the ideal version of you would finish, ask what today can support. A plan that only works on excellent days is not a plan; it is a fantasy schedule.

Keep three kinds of next actions:

• Deep: requires clear attention and uninterrupted time.
• Steady: ordinary work you can complete in a normal window.
• Light: small administrative or maintenance work for low-energy periods.

Choose from the right lane, not from one undifferentiated list. A light day is not a failed deep-work day. It is a different context.

Protect one deep action when conditions allow. On other days, make an honest smaller promise and keep it.
