Act as a productivity coach. I will provide a list of tasks for the upcoming week. For each task, categorize it as high-energy/complex, medium-energy/routine, or low-energy/simple. Then, assuming I have [number of time blocks] per day (e.g., 3 blocks: morning, afternoon, evening), assign each task to the most suitable block based on energy compatibility. Consider also deadlines and dependencies. Output a structured weekly plan with days and blocks, listing tasks with brief notes. Finally, suggest one small improvement to my workflow based on the plan. Task list: [insert task list with estimated duration and required energy level if known]
