Intro — "Worked 10 hours, wrote 100 lines — why?"

Almost every developer knows the feeling. Causes:

This post covers:

  1. Deep Work — Cal Newport, put into practice
  2. GTD — David Allen adapted for developers
  3. Calendar Blocking, Time-boxing, Pomodoro compared
  4. Meeting, Slack, Email triage
  5. Manager vs Maker schedule
  6. Burnout early signs and prevention
  7. Staying sharp in your 40s and 50s

Season 3 Episode 9. Last time, in "Finances," we said time compounds. This post is how to spend it.

Chapter 1: Deep Work — Why Depth Matters

1.1 Definition

Cal Newport (Deep Work, 2016):

"Deep Work: Professional activities performed in a state of distraction-free concentration that push your cognitive capabilities to their limit. These efforts create new value, improve your skill, and are hard to replicate."

The opposite is Shallow Work: logistics, email, meetings, repetitive tasks.

The modern knowledge-work trap: Shallow expands, Deep shrinks.

1.2 Why Developers Need It

Complex debugging, architecture design, learning new tech — all Deep Work.

1 hour Deep > 5 hours Shallow. Quality of focus beats quantity.

1.3 Four Modes of Deep Work

Monastic: Block all shallow. Why Knuth lives without email.

Bimodal: Alternate long monastic stretches with shallow. Example: two-week focus sprints while writing a paper.

Rhythmic: Same block every day (e.g. 6–9 AM).

Journalistic: Snatch Deep Work whenever possible. Requires practice.

1.4 Building the Environment

1.5 Daily Ceiling

You cannot do 8 hours of Deep Work. It is four sprints, not a marathon.

Chapter 2: GTD — Emptying the Mind

2.1 Five Stages

David Allen (Getting Things Done, 2001):

  1. Capture — move everything out of your head
  2. Clarify — decide what it means
  3. Organize — sort by category
  4. Reflect — regular review
  5. Engage — pick what to do now

2.2 Capture Tools

2.3 The Two-Minute Rule

Clarify stage:

"If it takes less than two minutes, do it now."

Reason: the cost of storing and tracking exceeds the cost of doing.

2.4 Contexts

Group tasks by where/how:

Developer variants:

2.5 Weekly Review

30–60 minutes once a week:

Without this, GTD falls apart.

2.6 Developer Adaptation

Capture:

Clarify/Organize:

Engage:

Chapter 3: Calendar Blocking

3.1 Definition

Assign every hour of the day to a block. Decide up front what happens when.

3.2 A Developer Day

08:00 - 09:00  Morning routine + exercise
09:00 - 11:30  Deep Work: core coding
11:30 - 12:00  Slack/Email triage
12:00 - 13:00  Lunch + reading
13:00 - 14:00  Meeting (weekly sync)
14:00 - 15:00  PR review
15:00 - 17:00  Deep Work: second block
17:00 - 18:00  1-on-1 / wrap-up
18:00+         Personal time

3.3 Buffer Rules

3.4 Protecting the Block

Google Calendar's Focus Time feature auto-declines and suppresses Slack alerts.

3.5 Obstacles

Chapter 4: Time-boxing

4.1 vs Calendar Blocking

Calendar Blocking assigns time to tasks. Time-boxing assigns a limit to each task (stricter).

4.2 Examples

4.3 Parkinson's Law

"Work expands to fill the time available."

No limit → infinite polishing. Limit set → priorities forced.

4.4 Practical Rules

Chapter 5: Pomodoro and the Ultradian Rhythm

5.1 Pomodoro

Pros: simple, easy to start. Cons: 25 minutes may cut flow right when it starts.

5.2 90-Minute Ultradian Rhythm

5.3 Flow State

Mihaly Csikszentmihalyi:

15–20 minutes to enter. A 25-minute Pomodoro never hits flow.

5.4 Recommendations

Chapter 6: Manager vs Maker Schedule

6.1 Paul Graham's Essay

Paul Graham (2009):

Manager's Schedule: one-hour slots. Meetings are default.

Maker's Schedule: 2–4 half-day blocks. A single meeting destroys a block.

Developers are makers. One morning meeting = morning Deep Work lost.

6.2 Clash and Fix

Manager:

Fixes:

6.3 "No Meeting Day" Culture

Many companies adopt it. Examples:

6.4 Staff+ Shift

Up to Senior, mostly Maker. Once Staff+, Manager duties grow.

Compromise:

Chapter 7: Slack, Email, and Meeting Triage

7.1 Slack Rules

As a sender:

As a receiver:

7.2 Email Triage

Daily Inbox Zero:

  1. Delete (spam, newsletters)
  2. Reply (under 2 minutes)
  3. Delegate (their job)
  4. Defer (add to todo)
  5. Archive (reference)

Time cap: 15 min morning, 10 min noon, 10 min evening.

7.3 Meeting Triage

Accept if:

Decline script:

"Thanks. If you can move forward without me, please share notes. Otherwise could we try next week?"

7.4 Fewer Meetings

Chapter 8: Burnout — Early Signs and Prevention

8.1 WHO Three Factors

  1. Emotional exhaustion — drained, depleted
  2. Depersonalization — "nothing matters"
  3. Reduced accomplishment — feeling ineffective

8.2 10 Early Signs

  1. Hard to get out of bed
  2. No interest in meetings
  3. Dread of Slack (even weekends)

  6. Weekends no longer recover you

9.4 Long-Lived Developers

Chapter 10: Time Management While Remote

10.1 Upsides and Traps

10.3 Avoiding Isolation

10.4 Async Culture

Chapter 12: 12-Item Productivity Checklist

Chapter 13: 10 Productivity Anti-Patterns

1) "Look Busy" Theater

Fast Slack replies to perform busyness. No real value. Visibility is not productivity.

2) Bragging About Multitasking

Three things at once. Context-switching cost 40%+. Single-task.

3) All Notifications On

Every app interrupts hundreds of times a day. Default OFF.

4) Meetings Feel Like Productivity

Eight hours of meetings = eight hours of output? Nothing got built.

5) "I Will Rest Later"

Rest after the project. Projects never end. Regular rest is non-negotiable.

6) Caffeine Abuse

4+ cups of coffee. Sleep ruined, anxiety up. None after 2 PM.

7) Late-Night Catch-Up

Meetings by day, code by night. Sleep destroyed. Defend Deep Work in daylight.

8) Chasing the Perfect Setup

Hours tuning Notion / Todoist. No real work. Ship at 80% setup.

9) "I Do Not Need Manuals"

Scorn checklists, repeat the same mistake. Checklists are professional.

10) Cannot Rest

Slack even on holiday. Rest is a skill. Practice it.

Closing — Time Is the Only Finite Resource

Principle 1: Productivity Grows From Health

Sleep, exercise, diet are the foundation. Any system fails without them.

Principle 2: Simple Beats Fancy

30 Notion templates < one page of notes + one todo. Simple beats polished.

Principle 3: Design the Day in Advance

Pick 3 MITs in the morning. Review at night. Those two moments are the core.

Principle 4: "No" Makes "Yes" Possible

Without refusal, no focus. Shield yourself from the unimportant.

Principle 5: Consistency Beats Perfection

A little every day beats a binge. Compounding wins.

Principle 6: Read the Originals
