B) Summarize progressively, at different levels of detail

A common problem with notes is that they are too long and dense. You can’t afford the time it would take to review and remind yourself of everything they contain. Executive summaries can help, but often it is a challenge to identify what exactly the main point is in the first place.

Progressive Summarization is a technique that relies on summarizing a note in multiple stages over time. You save only the best excerpts from whatever you’re reading, and then create a summary of those excerpts, and then a summary of that summary, distilling the essence of the content at each stage. These “layers” are like a digital map that can be zoomed in or out to any level of detail you need. Progressive Summarization allows you to read the note in different ways for different purposes: in depth if you want to glean every detail, or at a high level if you just need the main takeaway. This allows you to review a note’s contents in seconds to decide if it’s useful for the task at hand.
