I manage time but analyze: should I track energy instead? Map energy expenditure: tasks that drain vs. energize. Calculate: if energy management is more important than time management, how to track it? Show me the energy tracking: these tasks cost this energy, these generate energy. Give me the energy system: balance draining tasks with energizing ones. Include: what drains vs. energizes me, whether energy tracking would be more useful than time tracking, and how to maintain energy balance.
