• gives you compressed understanding with all the context
• Making a note discoverable involves making it small, simple, and easy to digest. We accomplish this using compression: creating highly condensed summaries, without all the fluff.
• But we also want to make our notes understandable. This involves including all the context: the details, the examples, and cited sources to be sure nothing falls through the cracks.

Layer 1: Take a note (by saving key excerpts from a book into a note-taking program)

Layer 2: Bold the best parts.

Layer 3: Highlight the best bolded parts.

Layer 4: Summarize the highlighted parts in your own words (at the top of the note)

Layer 5: Remix the note, turning it into a deliverable, such as a tweet, a tweetstorm, or blog post.

Don’t do this for every note!

If you follow the simple rule of summarizing a note every time you touch it, you’ll organically create a collection where the layers of summarization correspond to how integral that note is to your work. You can see at a glance how important a note is, without reading a word, just by how many layers it contains.
