Map Tasks to Daily Energy Levels

Help me optimize my task schedule based on my typical energy levels. My high-energy period is usually [e.g., 9 AM - 12 PM], medium energy is [e.g., 1 PM - 3 PM], and low energy is [e.g., 3 PM - 5 PM].

Here is my task list: [List tasks, potentially noting their required mental effort - e.g., - Write creative brief (High effort)
- Respond to routine emails (Low effort)
- Data analysis (High effort)
- Organize files (Low effort)]

Suggest an optimal time slot (morning, mid-day, afternoon) for each task based on its likely cognitive demand and my energy patterns.
