Keep a "Things I Don't Understand" List

Most people gloss over confusion and move on, pretending the gap doesn't exist. Instead, keep a running list of things you don't understand. Naming your confusion is the first step to resolving it. Vague discomfort with a topic stays vague forever; a specific written question becomes solvable.

Review your list weekly. Some items will resolve themselves as you learn more. Others will stubbornly persist — and those are the exact gaps that need your focused attention. Your confusion list is a map of your real learning frontier, not the frontier your curriculum assumes.
