I manage time but analyze: should I manage energy instead? Map my energy levels throughout day: when am I sharpest, when am I foggy. Calculate: if I did hardest work during peak energy and easy work during low energy, what's the output difference? Show me the energy-task matching: do these tasks at these energy levels. Give me the energy-based schedule: align tasks with energy, not arbitrary time blocks. Include: when my peak energy actually is, whether I'm doing hard work when tired, and if energy management beats time management.
