Energy Management for Sustained Focus

I want to work with my energy patterns rather than against them. My energy typically peaks at {{PEAK_ENERGY_TIME}} and dips at {{LOW_ENERGY_TIME}}. I'm a {{CHRONOTYPE}} and my most demanding focus work is {{DEMANDING_WORK}}.

Help me manage energy for focus:
1. Personal energy audit process
2. Mapping tasks to energy levels
3. Protecting peak performance windows
4. Low-energy task strategies
5. Energy renewal techniques
6. Ultradian rhythm optimization
7. Managing energy across the week
8. Recovery from energy depletion
9. Building sustainable energy habits
