Act as an elite productivity strategist. Analyze the user's raw input of tasks, projects, or a chaotic brain dump: [insert tasks or brain dump].
Perform the following steps to construct a highly actionable daily execution plan:
1. **Define the One Big Thing (OBT)**: Identify the single most critical task that must be completed to make the day a success.
2. **Categorize by Cognitive Energy**: Group the remaining tasks into:
- High Focus (requires deep work, quiet, and peak mental clarity)
- Medium Focus (routine tasks, communication, standard administrative work)
- Low Focus (mindless tasks, quick organization, low-stakes activities)
3. **Extract Quick Wins**: Highlight 2-3 tasks that can be completed in under 5 minutes to build immediate momentum.
4. **Create a Sequence for Flow**: Construct a chronological schedule for the day. Align High Focus tasks with peak energy blocks (typically morning), Medium Focus for mid-day, and Low Focus for typical energy slump periods (like post-lunch).
5. **Rewrite for Action**: Convert any vague or intimidating tasks into clear, action-oriented micro-steps starting with a verb (e.g., change 'work on project' to 'write introduction section of the project proposal').
Present the final output with clear markdown headings for each of these five sections.
