The idea of progressive summarization is to create notes such that their purpose is comprehensible in the future.
- Layer 1
- When you encounter something interesting, capture it
- Layer 2
- Bold the most interesting parts
- Layer 3
- Highlight the most interesting bolded sections
- Layer 4
- Summarize the bolded portions and the note in your own words
- Layer 5
- Turn your notes into something new: a tweet, a blog post, even a book
All of these steps are optional. I think of these as distillation, extracting key points from each note.
