Cal Newport's minimalist note-taking system for work and life

Executive overview

Most note-taking advice couples complicated software with elaborate philosophies. The result is friction that prevents you from capturing anything at all. Newport argues that for information capture — unlike deep writing — friction is the enemy.

The solution is three lightweight systems matched to context: physical marks in books, project-native storage for work, and a single aspirational notebook for life.

The core insight: your brain is part of the curation system — don't outsource everything out of it.

Why friction kills note-taking

• Friction is the overhead surrounding a task, not the task itself
• For long-form writing (e.g. John McPhee's scissors-and-plywood method), friction is beneficial — it forces slow thinking
• For information capture, friction means you simply don't capture; the information is lost
• Elaborate systems that aim to externalise everything remove your brain from filtering and prioritising
• When your brain has to remember "that book had important ideas about X," that act of remembering is a feature, not a bug

The corner marking method (books)

• Mark a diagonal line across the page corner whenever something is worth remembering
• In the margin, add small marks: box, checkmark, or curly brace next to key lines; occasional short scribble
• On returning to the book months or years later, scan only corner-marked pages and read the marked passages — roughly five minutes to reconstitute all important ideas
• Keeps a pencil in hand while reading; barely interrupts reading pace
• Requires remembering which book contained relevant ideas — this is intentional; if you can't remember, the book probably wasn't that useful

Project notes: store where you'll work

• Keep notes for a project in the tool you'll eventually use to produce it
• Articles and books → Scrivener research folder for that specific project
• Academic papers → Overleaf document for that paper; notes live in later sections, hidden once the paper takes shape
• Personal projects → a folder in Google Drive or equivalent
• Every time you add something new, you re-encounter all prior notes, triggering background processing and new angles
• Notes accumulate from the moment a project is conceived, even years before serious work begins

Life and ideas notebook

• A physical or digital notebook (Moleskine, Field Notes, reMarkable) reserved for ideas about life — not tied to any specific work project
• The aesthetic quality of the notebook matters; it signals a different mode of thinking
• No elaborate categorisation needed; the volume of life ideas is manageable in a way work notes are not
• Review when relevant (e.g. planning a new quarter, a specific opportunity arises)
• When filling a physical notebook, spend an hour copying only the most lasting ideas into the new one — natural triage

Gloria Mark's four myths of attention span

• Myth 1 — always strive to be focused: Attention is like muscle load; sustained strain is impossible and counterproductive
• Myth 2 — mindless activity is wasteful: The problem is not the activity itself but when it crowds out things you value; the tipping point is personal
• Myth 3 — distraction is caused by notifications and lack of discipline: Compulsive checking is driven by the collaboration structure (hyperactive hive mind) and addictive design, not notifications; discipline helps only indirectly, through building a life where shallow stimulation becomes optional
• Myth 4 — flow is the ideal state: Flow feels good but deliberate practice — doing things past your comfortable ability — is how you improve; TikTok-style flow is a trap

Advice on concentration and workload

• ADHD: intentional structure reduces the need to latch attention ad hoc; tight ritual can unlock hyperfocus as a superpower; customise advice with professional guidance
• Dissertation with full-time job: work on it first thing in the morning before the hyperactive hive mind depletes cognitive capacity; build a specific, repeatable ritual (see Brian Chappelle example in Deep Work)
• Afternoon productivity slump: the mind may be signalling the current pace is unsustainable; do less, end earlier, take longer on projects; no one will notice a shift from accepting 30% to 50% of requests; add a serious non-work interest and consider a digital declutter

On slowness as a concept

• "Slow" in Slow Productivity refers specifically to the unnaturally fast pace of modern knowledge work, not slowness as a universal virtue
• Moral urgency (Seneca, the opioid crisis) demands speed; pace of production work demands deceleration
• Slowness as jargon requires precision — name exactly what it applies to before adopting it
