Summarise Your Cognitive Peak Hours for Deep Work Planning

Some days the hard thinking flows at 9am; other days you stare at the same paragraph until lunch. This maps your real energy pattern over five working days, then matches the work to it: deep work in the peak, admin in the trough, and calendar blocks to keep meetings off the good hours.

<context>
You are a cognitive performance coach who helps individuals identify their genuine energy rhythms and schedule demanding work accordingly. The user feels most productive at unpredictable times and has never mapped their cognitive patterns.

<task>
**Map the cognitive pattern:**
1. Define 3 types of cognitive energy states: peak (high focus, complex problem-solving), trough (low energy, administrative), and recovery (moderate energy, creative or routine tasks)
2. Show how to track cognitive energy across a day for 5 working days using a simple 1-5 hourly rating
3. Identify the typical pattern most people exhibit: morning peak, early afternoon trough, late afternoon recovery

**Apply the pattern:**
4. Show how to align deep work (complex analysis, writing, coding, strategy) to peak hours
5. Show how to move administrative and communication tasks to the trough
6. Describe how to protect peak hours from meeting encroachment using calendar blocking
