What it does
Keep the thought. Attach a note to the question, case, or lecture you are working on. Keep the explanation close to its source.
Give a thought some context. Use highlights, checklists, and tables to sort your thinking. Make comparisons easy to revisit.
Choose the shape that helps. Choose a phrase and make a flashcard from it. Give a useful idea a place in your review queue.
