The CODE Cycle
The CODE cycle (Collect → Organize → Distill → Express) turns scattered knowledge into actionable insights by moving information through refinement stages.

Collect: Capture information from multiple sources such as books, articles, thoughts, quotes etc. Extract the core idea and give proper annotations for future reference. The process may vary based on your capture-system but the core principle remains the same.
Organize: Structure data for retrieval using tags, categories, or links. This is the part where you find place for this new information amongst the pre-existing knowledge base. This becomes your second-brain.
Distill: Extract key takeaways, discard fluff. You don't need to store the entire article or extract if the whole idea can be explained in one sentence.
Express: Transform refined knowledge into creative output. This could mean anything for you. You can learn-in-public 1 using a digital-garden or blogs or videos. Share your knowledge or teach shat you've mattered. Or share in forms of stories or creative work.Without expression there is no real point of the stored knowledge.
Real knowledge grows in the stage 3 and 4 otherwise one may just be trapped in collectors-fallacy which may feel productive but doesn't do anything.
