Keep a place for unfinished thoughts
An idea does not need to be ready before it goes on paper. A few rough lines are often enough to find the next step.
Notes & observations
Collected along the way.
Brief observations, reading notes and small discoveries.
From the notebook
Read with a pencil nearby
Mark a sentence that stays with you. Return to it a week later and write down what changed in the way you understood it.
A list for the end of the day
Name one thing you noticed, one thing you learned and one thing you want to revisit. Three lines can tell a surprisingly complete story.
