Summarise What You Actually Got From a Course or Book

The course or book is finished and you felt something shift at the time. Three weeks later the notes are in a folder and the feeling has mostly faded. This separates the one idea that actually changed how you think from what was interesting but did not stick, identifies what has genuinely changed in your behaviour, surfaces the open question the material raised, and gives you one specific thing to do in the next two weeks so the investment does not just live in highlights.

Extract and summarise the genuine, lasting learning from the course or book described, separating what has actually changed in how you think or act from what was interesting but did not stick.

1. The core insight: the one idea from the course or book that genuinely changed something about how you think, decide, or behave, stated in your own words
2. What has actually changed: two or three specific ways the material has changed your behaviour, perspective, or decisions since engaging with it
3. What did not stick: one idea or framework from the material that seemed important at the time but has not changed anything in practice, and why
4. The open question: the most important question the material raised that you have not yet resolved
5. What to do with it next: one specific action in the next two weeks that would make better use of the material than leaving it in notes
