From Collector to Creator
Many note-takers hoard content because it gives them an illusion of knowledge as collectors-fallacy. The best way to tackle this issue and process the content with high level of understanding is to use the generation effect: to produce your own content, in your own words and share it with the world to create a feedback loop.
the-code-cycle is an amazing system to follow through on the content you're consuming and ensures you're outputting something of equal or greater value than what you're consuming.
Collect: note taking, clipping, highlights, extracts etc.
Process: cleaning up, linking, categorising and tagging.
Create: producing content based on the gathered information and your own understanding of everything in your words and your viewpoint.
