Burnout vs Regular Tiredness
================================

Regular Tiredness:
- Recovers with rest
- Motivation persists
- Has a specific cause
- Temporary

Burnout:
- Does NOT recover with rest
- Motivation disappears
- Cumulative, complex causes
- Chronic
- Cynicism develops
- Professional efficacy drops

Burnout Self-Assessment
================================
[ ] Mornings feel extremely difficult to start work
[ ] Looking at code itself feels repulsive
[ ] Programming that you once enjoyed is no longer fun
[ ] Small bugs trigger excessive irritation
[ ] You want to avoid conversations with colleagues
[ ] Weekends are consumed by Monday dread
[ ] Concentration has dropped dramatically
[ ] Physical symptoms: headaches, insomnia, digestive issues
[ ] "Things would run fine without me" thoughts
[ ] No energy even outside of work hours
[ ] Code review requests feel like a burden
[ ] Questioning your entire career

Healthy Boundary Examples
================================

Work Hours:
  Start: 9:00 AM
  End: 6:00 PM
  Lunch: 1 hour (completely away from screen)

Communication:
  Slack: Notifications ON only during work hours
  Email: Check 3x/day only (morning/after lunch/before end)
  On-call: Clear rotation + compensation

After Work:
  Work Slack: Notifications OFF
  Coding: Only when you WANT to (not obligated)
  Learning: Limited to 3 hours/week max

Burnout Recovery Roadmap
================================

Phase 1 - Acknowledge (Week 1)
  Accept "I am currently burned out"
  Talk honestly to manager/colleagues

Phase 2 - Decelerate (Weeks 2-4)
  Reduce workload (negotiate with manager)
  Temporary removal from on-call
  Take PTO if possible

Phase 3 - Recharge (Months 1-3)
  Resume hobbies
  Start exercise routine
  Improve sleep habits
  Seek professional help if needed (EAP)

Phase 4 - Rebuild (Months 3-6)
  Set new boundaries when returning
  Introduce productivity routines
  Find a sustainable pace

Pomodoro Basics
================================

25min focus -> 5min break -> 25min focus -> 5min break
-> 25min focus -> 5min break -> 25min focus -> 15-30min long break

4 Pomodoros = 1 Set

Developer Variations:
- 50min focus + 10min break (complex coding)
- 90min focus + 20min break (deep work sessions)

Recommended Tools:
- Focus To-Do (iOS/Android)
- Forest (gamified focus app)
- Be Focused (macOS)

Deep Work Implementation
================================

Environment Setup:
  [1] Set Slack/Teams status to "Focusing"
  [2] All notifications OFF (DND mode)
  [3] Phone in another room
  [4] Noise-canceling headphones ON
  [5] Minimize browser tabs (IDE + essential only)

Time Allocation:
  - 9:00-11:30 AM: Deep Work 1 (hardest tasks)
  - 2:00-4:00 PM: Deep Work 2 (implementation)
  - Remaining: Meetings, code review, email (shallow work)

Daily Deep Work Target: 3-4 hours
(This is sufficient. The average knowledge worker manages only 1.5 hours.)

Ideal Developer Day (Time Blocking)
================================

06:30 - 07:00  Wake up, drink water, light stretching
07:00 - 07:30  Walk or meditation
07:30 - 08:30  Breakfast + news/learning
08:30 - 09:00  Daily planning, email check

09:00 - 11:30  [Deep Work 1] Core development
11:30 - 12:00  Slack check, quick code reviews

12:00 - 13:00  Lunch + 20-minute walk (away from screens)

13:00 - 13:30  Email/Slack responses
13:30 - 15:30  [Deep Work 2] Development/design
15:30 - 16:00  Snack + stretching

16:00 - 17:00  Meetings, code reviews, pair programming
17:00 - 17:30  Prepare for tomorrow, wrap up Slack
17:30 - 18:00  Learning or reading tech blogs

18:00+         Off work (complete separation)

Energy Management Principles
================================

High Energy (typically morning):
  -> Most difficult, creative tasks
  -> Algorithm design, architecture decisions
  -> Bug hunting, new feature implementation

Medium Energy (typically early afternoon):
  -> Implementation, refactoring
  -> Code reviews, documentation

Low Energy (typically late afternoon):
  -> Email, Slack responses
  -> Simple bug fixes
  -> Learning, reading tech blogs

Energy Recharging:
  - 10-minute power nap
  - 5-minute stretching
  - Short walk (5-10 minutes)
  - Drink water
  - Snack (nuts, fruit)

GTD for Developers
================================

1. Capture:
   Collect all tasks in one place
   - Jira/Linear tickets
   - Personal TODO (Todoist, Notion)
   - Action items extracted from Slack

2. Clarify:
   Define the next action for each item
   - "Implement login" -> "Design login API endpoint"
   - "Improve performance" -> "Profile bottleneck with profiler"

3. Organize:
   Categorize by context
   - @coding: Tasks requiring focused coding
   - @review: Code reviews
   - @meeting: Items to discuss in meetings
   - @learning: Things to learn
   - @waiting: Waiting for others' responses

4. Reflect:
   Weekly review (Friday, 30 min)
   - What was completed this week
   - Next week's priorities

5. Engage:
   Pick tasks matching current context and energy

Recommended Morning Routine (First Hour)
================================

Immediately After Waking (0-5 min):
  [1] Get up immediately (no snooze)
  [2] Drink water (500ml)
  [3] Open curtains / expose to bright light

First 15 Minutes:
  [4] Light stretching or yoga (5-10 min)
  [5] Meditation or deep breathing (5 min)

Next 15 Minutes:
  [6] Shower

Sleep Hygiene Checklist
================================

Bedroom Environment:
  [ ] Temperature: 65-68F / 18-20C (cool)
  [ ] Blackout curtains or sleep mask
  [ ] Noise blocking (earplugs or white noise)
  [ ] Comfortable mattress and pillow

Pre-Sleep Routine (1 hour before bed):
  [ ] Blue light blocked (phone, monitor OFF)
  [ ] No caffeine (from 8 hours before bed)
  [ ] No alcohol (degrades sleep quality)
  [ ] Light stretching or meditation
  [ ] Warm shower or bath

Sleep Schedule:
  [ ] Same sleep and wake time daily
  [ ] Weekend variation within 1 hour
  [ ] Target 7-9 hours of sleep

Blue Light Management
================================

Evening (2 hours before bed):
  - Activate Night Shift / Night Light mode
  - Install f.lux or similar app
  - Wear blue-light blocking glasses

Fundamental Solution:
  - All screens OFF 1 hour before bed
  - Instead: physical books, journaling, light conversation
  - E-ink devices are OK (Kindle, etc.)

Developer-Specific Tips:
  - IDE Dark Mode (VS Code, IntelliJ)
  - Terminal Dark Theme too
  - When coding at night, brightness under 50%

Developer Caffeine Management
================================

Caffeine Half-Life: approximately 5-6 hours
(Time for one cup's caffeine to drop by half)

Recommended Pattern:
  First coffee 90 min after waking (when cortisol drops)
  No caffeine after 1:00 PM
  Total daily caffeine under 400mg (about 3-4 cups)

Caffeine Alternatives:
  - Decaf coffee (taste without caffeine)
  - Green tea (L-theanine for smoother alertness)
  - Water (dehydration is a major fatigue cause)
  - Short walk (natural energy boost)

Effective Power Nap Guide
================================

Optimal Time: 1:00-3:00 PM
Optimal Duration: 10-20 minutes (over 30 = sleep inertia)

Method:
  1. Set alarm (20 minutes)
  2. Drink coffee then immediately nap (coffee nap)
     - Caffeine takes about 20 min to kick in
     - Synergy with waking alertness
  3. Dark, quiet place
  4. Falling fully asleep is not required (eyes closed helps)

Caution:
  - Avoid after 4 PM (disrupts nighttime sleep)
  - Avoid over 30 minutes (wake up groggier)

Brain Foods for Developers
================================

Top Brain Foods:
  - Blueberries: Antioxidants, memory improvement
  - Salmon/Mackerel: Omega-3, brain function
  - Walnuts: Healthy fats for brain health
  - Dark chocolate (70%+): Concentration boost
  - Eggs: Choline, memory and mood
  - Spinach/Kale: Vitamin K, cognitive function
  - Avocado: Healthy fats, blood flow improvement

What to Avoid:
  - Excess processed sugar (causes energy crashes)
  - Excessive junk food (triggers inflammation)
  - Heavy drinking (degrades sleep, impairs cognition)

Hydration Guide
================================

Target: 2-3 liters per day

Practical Steps:
  - 500ml immediately after waking
  - Always keep a water bottle at your desk
  - One glass during each Pomodoro break
  - One glass before meals
  - One glass before and after exercise

Dehydration Signs:
  - Difficulty concentrating
  - Headaches
  - Fatigue
  - Dark urine

Tip: If plain water is boring, add lemon, cucumber, or mint

Weekly Meal Prep Guide
================================

Invest 2 hours Sunday for the whole week:

Prepare:
  1. Brown rice or quinoa (bulk cook)
  2. Chicken breast or salmon (grill or oven)
  3. Hard-boiled eggs (10)
  4. Stir-fried vegetables (broccoli, carrots, peppers)
  5. Pre-portioned healthy snacks (nuts, fruit)

Lunch Container:
  - 1/4 carbs: Brown rice or sweet potato
  - 1/4 protein: Chicken, salmon, tofu
  - 1/2 vegetables: Variety of colors
  - Good fats: Avocado, olive oil dressing

Mindset Comparison
================================

Fixed Mindset:
  "I'm a frontend dev, I can't do backend"
  "This algorithm is too hard, it's beyond me"
  "Code review feedback = criticism of me"
  "Other devs are geniuses, I'm the only one struggling"

Growth Mindset:
  "I can learn backend too"
  "I can't solve this algorithm YET, but with practice I will"
  "Code review feedback = growth opportunity"
  "Other devs also took a long time to reach that level"

Practice Shifts:
  "I can't" -> "I can't YET"
  "I failed" -> "I learned"
  "This is too hard" -> "This is challenging"

Imposter Syndrome Strategies
================================

1. Recognize It:
   "This feeling is imposter syndrome. Many developers feel this."

2. Collect Evidence:
   - List bugs/tickets you've resolved
   - Record positive feedback received
   - Keep a growth journal (you 1 year ago vs now)

3. Stop Comparing:
   - Don't compare GitHub contribution graphs
   - Don't compare others' "highlights" with your "behind-the-scenes"
   - Limit time on tech community social media

4. Share Vulnerability:
   - Tell colleagues "I find this difficult too"
   - Consult with a mentor
   - Share experiences in communities

5. Recognize the Curse of Knowledge:
   - What you know seems obvious to you
   - But it's not to a beginner
   - Your "obvious knowledge" is valuable to someone

Healthy Code Review Mindset
================================

As a Reviewer:
  - Critique the code, not the person
  - "What led you to choose this approach?" (curiosity)
  - "How about trying this?" (suggestion)
  - Mention positive aspects too (praise)

As a Reviewee:
  - Feedback is about the CODE, not about YOU
  - It's OK to ask "why?" (for understanding, not defense)
  - It's OK to disagree (with supporting reasoning)
  - Be grateful for learning from feedback

Practical Tips:
  - Self-review before submitting a PR
  - Wait 20 minutes before responding to feedback (prevent emotional reactions)
  - Treat repeated feedback as a learning opportunity

When Developers Need to Say "No"
================================

Situations to Say No:
  - Already overloaded, but asked for more
  - Unrealistic deadlines
  - Tasks outside your expertise being pushed on you
  - After-hours requests (non-urgent)

How to Say It:
  "I'm currently focused on Project A, so I can't take on
   new work. I can start once A is done next week."

  "That deadline isn't realistic.
   If we cut feature X, we can make it."

  "Team Y would be a better fit for this task.
   I can connect you with them."

Key: Saying "no" is not selfish - it's professional.

Digital Boundary Guide
================================

After Work:
  - Slack/Teams: Notifications OFF (except emergency channels)
  - Work email: Don't check
  - Work laptop: Close it (physically)

Weekends:
  - Work-related learning is optional
  - Code only when it's fun
  - At least one day completely digital-free

Vacation:
  - Actually rest (no work Slack/email)
  - Thorough handoff before leaving
  - "Emergency contact" for true emergencies only

Healthy Side Project Management
================================

To prevent side projects from causing burnout:

Rules:
  1. Limit to 5 hours/week
  2. No deadlines (fun is the purpose)
  3. A playground for trying new tech
  4. Not finishing is OK
  5. Choose a different domain from work

Good Side Project Examples:
  - Personal blog (any topic)
  - Making games (fun!)
  - Open source contributions (start small)
  - Learning a new language (Rust, Go, etc.)

Warning Signs:
  - Side project feels like an obligation
  - Weekends are consumed by side projects
  - Side projects are cutting into your sleep
  -> Immediately stop or scale down

Simple Meditation Guide for Developers
================================

1-Minute Breathing (Anytime):
  - Close eyes
  - Breathe in for 4 seconds
  - Hold for 7 seconds
  - Breathe out for 8 seconds
  - Repeat 3 times

5-Minute Mindfulness (Morning/After Lunch):
  - Sit comfortably
  - Focus on breath
  - When thoughts arise, let them pass without judgment
  - Return focus to breath

Recommended Apps:
  - Headspace: Guided meditation, beginner-friendly
  - Calm: Sleep stories, nature sounds
