Example

Scenario: Engineer overwhelmed with tickets, meetings, code reviews, and a complex feature.

80/20: Ship payment feature (biggest customer request, revenue impact) = vital 20%.

Weekly Plan:

• Mon-Wed mornings (9-12): Deep work on payment feature (no meetings, Slack off)
• Mon-Wed afternoons: Code reviews, standups, pair programming
• Thu-Fri: Batch meetings, planning, admin, lower-priority tickets

Outcome: Feature shipped in 3 days (18 hours deep work) vs. estimated 2+ weeks with constant interruptions.

Focus & Timeboxing Progress:
- [ ] Step 1: Identify your 80/20
- [ ] Step 2: Design focus blocks
- [ ] Step 3: Timebox your week
- [ ] Step 4: Timebox your day
- [ ] Step 5: Execute with discipline
- [ ] Step 6: Review and adjust

Step 1: Identify your 80/20

What 20% of tasks drive 80% of your results? Separate vital few from trivial many. See resources/template.md.

Step 2: Design focus blocks

Block time for deep work on high-impact tasks. Match duration to task type (Pomodoro 25min, Deep Work 90-120min). See resources/template.md and resources/methodology.md.

Step 3: Timebox your week

Allocate weekly calendar: deep work blocks, meeting blocks, batched admin, buffer time. See resources/template.md and resources/methodology.md.

Step 4: Timebox your day

Break day into time-constrained blocks with start/end times. Schedule breaks. Plan evening hard stop. See resources/template.md.

Step 5: Execute with discipline

Honor timeboxes. Use timers. Eliminate distractions (Slack off, phone away, close tabs). Take breaks. See resources/methodology.md.

Step 6: Review and adjust

Weekly review: Did you protect deep work? What interrupted focus? Adjust schedule. See resources/template.md and resources/methodology.md.

Common Patterns

Pattern 1: Pomodoro Technique (25 min focus)

• Format: 25 min focused work + 5 min break, repeat 4×, then 15-30 min break
• Best for: Tasks with high resistance (procrastination), need for frequent breaks, building focus habit
• Tools: Timer, task list, distraction blockers
• When: Short tasks, starting new habits, high-distraction environments
• Guardrails: Don't interrupt Pomodoro mid-session, actually take breaks (don't skip)

Pattern 2: Deep Work Blocks (90-120 min)

• Format: 90-120 min uninterrupted focus on single cognitively demanding task
• Best for: Complex thinking (writing, coding, design, strategy), high-value creative work
• Preparation: Clear goal for session, all resources ready, distractions eliminated
• When: Peak energy hours (usually morning), maximum 2-3 blocks per day
• Guardrails: No meetings during deep work, Slack/email off, phone in another room

Pattern 3: Weekly 80/20 Planning

• Format: Sunday/Monday - identify top 3 high-impact goals for week, schedule deep work blocks
• Best for: Strategic prioritization, ensuring vital few get attention
• Output: 3-5 focus blocks (90-120 min each) on calendar for week's top priorities
• When: Start of week, quarterly planning, project kickoffs
• Guardrails: Protect these blocks ruthlessly, treat like unmovable meetings

Pattern 4: Task Batching (30-60 min blocks)

• Format: Group similar low-cognitive-load tasks (emails, calls, admin) into single session
• Best for: Reducing context-switching, clearing small tasks efficiently
• Examples: Email batches (11am, 4pm), meeting blocks (Tue/Thu afternoons), admin Fridays
• When: Low-energy periods, after deep work, end of day
• Guardrails: Set timer, don't let batches expand, resist checking email outside batches

Pattern 5: Maker's Schedule (Half-day or Full-day blocks)

• Format: Uninterrupted half-days (4+ hours) or full days for creative/technical work
• Best for: Large projects (research paper, product launch, complex feature), flow-state work
• Preparation: Clear all meetings for that period, OOO on Slack, backup plan if interrupted
• When: Critical deadlines, breakthrough work needed, once/week minimum for makers
• Guardrails: Communicate boundaries, delegate urgent issues, plan breaks within block

Pattern 6: Energy-Based Scheduling

• Format: Match task type to energy level (peak → deep work, trough → admin, recovery → meetings)
• Best for: Maximizing output while preventing burnout
• Typical cycle: Peak (9am-12pm) → Trough (2-3pm) → Recovery (4-5pm)
• When: Designing weekly/daily schedules, recovering from overwork
• Guardrails: Track your actual energy patterns (not generic), honor low-energy periods with rest

Guardrails

1. Protect deep work time: No meetings, no Slack, no email during focus blocks. One interruption destroys 20+ minutes of flow. Schedule deep work during peak energy (usually mornings).

2. Use Parkinson's Law: Work expands to fill available time. Shorter timeboxes force prioritization and prevent perfectionism. A 90-minute timebox with a clear outcome beats open-ended "work on this."

3. Identify the 80/20: Force rank tasks by impact. The top 20% should get 80% of focus time. Cut, delegate, or batch the rest.

4. Energy matters more than time: 8 hours tired produces less than 4 hours energized. Match intensity to energy level. Troughs are for admin and meetings, not complex thinking.

5. Build in buffer: Leave ~20% unscheduled for unexpected issues, overflow, and breaks. Over-scheduling is fragile; one delay cascades.

6. Set hard stops: Define an end-of-day time. Constrained time forces prioritization; endless time enables procrastination.

7. Take breaks: After 90 minutes of deep work, take 10-15 minutes. Walk, stretch, look outside. Focus degrades after 90-120 minutes without a break.

8. Measure focus quality, not hours: 3 hours of deep work outperforms 8 hours of distracted work. Track completed focus blocks per week, not total hours.

Common pitfalls:

• ❌ No real deep work blocks: Calendar full of meetings, "focus time" constantly interrupted. Protect minimum 2-3× 90-min blocks per week.
• ❌ Ignoring 80/20: Everything feels important. Force rank. If you can't identify top 20%, ask: "If I could only work 10 hours this week, what would I do?"
• ❌ Timeboxing trivia: Scheduling every email, every Slack message. Batch low-value tasks, don't timebox them individually.
• ❌ Skipping breaks: "I'll break after I finish this." Then work 4 hours straight, output quality tanks. Use timer, force breaks.
• ❌ Peak hours on admin: Checking email at 9am (peak energy). Save admin for afternoon trough. Peak hours = deep work only.
• ❌ Overcommitting: Timeboxing 10 hours of work into 8-hour day. Be realistic. Under-schedule, over-deliver.

Quick Reference

Timeboxing durations:

Duration	Best For	Rest After
25 min	Pomodoro, high-resistance tasks, building habit	5 min
50 min	Focused work, moderate complexity	10 min
90 min	Deep work, complex thinking, creative tasks	15 min
120 min	Maximum deep work (rare, high expertise)	20-30 min
Half-day (4h)	Maker's schedule, breakthroughs, flow state	Lunch + afternoon off

Energy-based scheduling:

Time	Energy Level	Task Type	Examples
6-9am	Peak (early risers)	Deep work	Writing, coding, strategy
9am-12pm	Peak (most people)	Deep work	Complex problems, creative work
12-2pm	Lunch dip	Meetings, social	Standups, 1:1s, collaboration
2-3pm	Trough	Admin, batching	Email, Slack, expense reports
3-5pm	Recovery	Moderate work	Code reviews, planning, lighter tasks
Evening	Low	Rest or routine	Reading, exercise, NOT deep work

80/20 identification:

Ask these questions:

• "If I could only work 10 hours this week, what would I do?"
• "Which tasks, if done well, make everything else easier or unnecessary?"
• "What creates 10× value vs. 1× value?"
• "What will matter in 6 months? What won't?"

Focus blockers (eliminate during deep work):

• Slack/Teams (quit app or set DND)
• Email (close tab/app)
• Phone (different room, airplane mode)
• Browser tabs (close all except work-related)
• Open floor plans (noise-canceling headphones, office door)
• Notifications (disable all)
• Meetings (schedule-free mornings)

Batching categories:

• Email batches: 11am, 4pm (2× per day max)
• Meeting blocks: Tue/Thu afternoons
• Admin batch: Friday afternoons (expense reports, timesheets, planning)
• Code review batch: After lunch (30-60 min)
• Quick calls batch: 30-min slots back-to-back

Weekly planning template (simplified):

Monday-Wednesday mornings: Deep work on Priority 1 (3× 90-min blocks)
Monday-Wednesday afternoons: Meetings, collaboration, moderate work
Thursday: Deep work on Priority 2 (morning), meetings (afternoon)
Friday: Batched admin, planning next week, code reviews

Inputs required:

• Current commitments: Meetings, recurring tasks, deadlines
• Energy patterns: When are you most/least energized? (track for 1 week)
• Top priorities: What are your 3-5 most important outcomes this week/month?
• Task list: Everything competing for attention (to identify 80/20)
