Take Notes from Books
You finish a book, feel smarter for a week, then forget everything in it. Reading without notes is entertainment; reading with notes is learning. The trick is a light system — not transcribing the book, but capturing the few ideas worth keeping.
TL;DR / Quick Fix
Quick fix: take book notes by capturing one idea per chapter in your own words — not copying passages. Review the notes a week later and keep only what still matters. A few kept ideas beat fifty forgotten highlights. Store them in one place you will actually revisit.
Follow these steps
- Read with a pen nearby. Mark passages as you go — a star in the margin, a folded corner. Marking while reading is cheap; deciding what matters comes later.
- Write one idea per chapter. After each chapter, close the book and write the main idea in your own words. If you cannot, you did not get it — reread, or see the Feynman approach.
- Capture quotes sparingly. Copy only lines you will actually reuse — a handful per book. Fifty highlights are a second book you will never reread.
- Review within a week. Notes decay fast. A ten-minute review a few days later moves ideas from short-term memory into something durable.
- Keep notes in one place. A single notebook or one notes app beats scattered sticky notes. One home means notes get revisited.
- Connect new notes to old ones. When a new idea echoes an older note, link them. Connected notes compound; isolated notes fade.
What NOT to do
- Do not transcribe whole chapters. Copying is not learning — your own summary is.
- Do not highlight everything. If half the book is highlighted, nothing is.
- Do not take notes you will never review. Unreviewed notes are just slower reading.
- Do not use a complicated system at first. One notebook and a pen beats a tagging scheme you abandon.
Frequently asked questions
Paper or digital notes?
Whichever you will review. Paper aids memory for many; digital is searchable. Pick one and commit.
How many notes per book?
Five to fifteen kept ideas is a rich harvest. More usually means you have not filtered.
What about audiobooks?
Pause and dictate or jot the idea immediately — audiobooks evaporate fastest without notes.
