Set a guiding question before you open a book or article, and keep it visible while reading. Purpose filters what you mark, steering you toward ideas that serve a project or curiosity, while protecting you from hoarding impressive, but irrelevant, sentences.
When you highlight, add a brief note about why it matters, what it connects to, and how you might use it. A sentence of context turns a lonely excerpt into a usable idea, especially months later when memory and enthusiasm have faded.
Always capture author, title, publication, date, and link or page numbers alongside each highlight. This small habit saves hours when you cite, revisit, or share, and it quietly raises your standards because unverifiable claims become obviously unfit for serious writing.
