The Architecture of Focus
A deep work session is not a to-do list. It's a systematic process that moves work from start to finish with minimal friction. Each phase has a specific purpose, and work flows smoothly from one to the next. Most people's workdays are chaotic—they constantly search for tools, context, and direction.
The goal isn't to work harder. It's to design work sessions so intelligent that progress happens almost automatically. Your energy should go to the work itself, not to figuring out how to work.
The Four Stations of a Work Session
Station 1: Prepare
Set up your environment. Clear your space. Gather what you need. Close unnecessary tabs. Put phone away. Physical preparation precedes mental focus.
Station 2: Plan
Set your direction. What exactly will you accomplish? What's the first step? How will you know you're done? Clarity before action.
Station 3: Execute
Do the work. Uninterrupted focus. No context switching. No checking email. No "quick" distractions. Just the work.
Station 4: Review
Capture and close. What did you accomplish? What's next? Where did you get stuck? Document before you forget.
Deep Work vs Shallow Work
Deep Work
- Cognitively demanding
- Creates new value
- Hard to replicate
- Moves important projects forward
- Requires uninterrupted focus
- Examples: Writing, coding, designing, strategizing, learning
Shallow Work
- Logistically necessary
- Maintains existing value
- Easy to replicate
- Keeps things running
- Can be done with distractions
- Examples: Email, meetings, admin, coordination
The Question
Most people spend 80% of their time on shallow work and wonder why they're not making progress. What would happen if you reversed those numbers?
The 90/20 Rhythm
Work with your brain's natural rhythm
Your brain naturally works in 90-120 minute cycles of high focus, followed by 20-30 minutes of lower energy. Fighting this rhythm is fighting your biology.
The 90/20 rhythm:
- 90 minutes of deep, uninterrupted work
- 20 minutes of true rest (walk, stretch, hydrate, no screens)
- Repeat up to 3-4 times per day
This isn't "wasting time"—it's working with your biology instead of against it.
The Deep Walk Protocol
Prepare (5 minutes)
Clear your space. Close unnecessary tabs. Put phone in another room. Gather what you need. Physical preparation precedes mental focus.
Plan (2 minutes)
Set a timer for 90 minutes. Write down one specific goal: "What will I have accomplished when the timer goes off?"
Execute (90 minutes)
No interruptions. No context switching. If unrelated thoughts come up, write them down quickly and return to the work. Stay with the task until the timer ends.
Review (3 minutes)
When the timer ends, stop. Write down: What did you accomplish? What's next? Any insights or stuck points?
Rest (20 minutes)
True rest. Walk, stretch, hydrate, look at something distant. No screens. Let your brain recover before the next block.
This Week's Practice
Day 1-2: Audit
Track your work for 2 days. How much deep work? How much shallow work? How many interruptions?
Day 3-4: One Deep Block
Schedule and protect one 90-minute deep block each day. Follow the protocol exactly.
Day 5-6: Batch Shallow Work
Schedule shallow work (email, admin) in batches. No shallow work during deep blocks.
Day 7: Review
Compare your progress this week to last week. What changed?
One hour of deep work is worth more than eight hours of shallow, distracted effort. Protect your deep blocks fiercely.
