## Planning Principles (Research-Backed)

1. **Circadian optimization** - Cognitive performance peaks ~2-3 hours after waking (Roenneberg, 2012)
2. **Ultradian rhythms** - Work in 90-minute blocks with 15-20 minute breaks (Ericsson, 1993)
3. **Decision fatigue prevention** - Schedule high-stakes decisions before 3pm (Kahneman, 2011)
4. **Implementation intentions** - Specific time+task combinations increase completion by 2-3× (Gollwitzer, 1999)

## Energy Windows (Default - Customize Yours)

**Peak Performance (Morning):** 9:00 AM - 12:00 PM
- Deep work, strategic thinking, complex problem-solving
- Highest cognitive capacity
- Schedule your #1 priority here

**Secondary Peak (Afternoon):** 2:00 PM - 4:00 PM
- Focused work, meetings with decisions, creative work
- Still high capacity but slightly lower than morning

**Administrative (Late Afternoon):** 4:00 PM - 6:00 PM
- Email processing, light tasks, 1-on-1s, planning
- Lower energy, avoid complex decisions

**Recovery Blocks:** 12:00 PM - 1:00 PM, 6:00 PM+
- Meals, exercise, walks, recharge
- Non-negotiable for sustained performance

**Wind Down (Evening):** After 7:00 PM
- Reflection, reading, light planning for tomorrow
- No high-cognitive work

## Process

### 1. Gather Context (30 seconds)
- Check existing calendar events
- Review yesterday's incomplete tasks
- Identify any fixed commitments or deadlines
- Note current project priorities

### 2. Identify Top 3 Priorities (60 seconds)
Ask for each potential priority:
- **Impact:** Does this move a key metric or deadline?
- **Urgency:** Must it happen today?
- **Effort:** Can I complete it in available time?

**Filter:** Pick the 3 with highest impact×urgency score

### 3. Build Time-Blocked Schedule (90 seconds)
**Sequencing logic:**
1. Place fixed commitments (meetings, calls) first
2. Assign Priority #1 to longest peak energy block
3. Assign Priority #2 to secondary peak or next available
4. Assign Priority #3 to remaining focused time
5. Add 20-minute buffers between major blocks
6. Schedule admin work (email, Slack) in low-energy windows
7. Protect breaks and meals (non-negotiable)

**Buffer rule:** Only schedule 80% of available time

### 4. Apply Constraints
- **Personal boundaries:** No work before 8am or after 7pm (customize)
- **Meeting limits:** Max 4 hours of meetings per day
- **Focus blocks:** Minimum 90 minutes for deep work (no interruptions)
- **Break enforcement:** 15-minute break every 90 minutes

## Output Format

## Real Examples

### Example 1: High-Output Day (Founder/Exec)

**Context:** Product launch week, high-stakes demos, team coordination

### Example 2: Deep Work Day (Individual Contributor)

**Context:** IC developer, needs 6+ hours of uninterrupted coding

### Example 3: Meeting-Heavy Day (Manager/Director)

**Context:** Leadership role, multiple teams, coordination day

## Real Case Study

**User:** Marketing manager at B2B SaaS company, struggled with reactive days

**Before using skill:**
- Average day: 6-8 hours in meetings, 2 hours of "work" squeezed in
- Top priorities rarely completed
- Constant email/Slack interruptions
- 15% weekly goal completion rate
- Felt productive but accomplished little

**After implementing plan-my-day:**
- Used skill every morning (2-3 minutes to generate plan)
- Protected 9-11am deep work block (calendar marked "Focus Time")
- Set clear Top 3 priorities each day
- Added evening check-ins to track completion

**Results after 8 weeks:**
- 74% weekly goal completion rate (+59 points)
- Meetings reduced from 6-8 hrs/day to 3-4 hrs/day
- Deep work blocks protected 4 days/week (vs 0 before)
- Self-reported energy levels: 8.2/10 (vs 4.1/10 before)
- Team feedback: "You're more present and decisive"

**Key insight:** "The daily plan gave me permission to say no. If it wasn't in my Top 3, I deferred it. That one change unlocked everything."
