CODE Framework
This is part of the PARA method of Personal Knowledge Management.
Capture
Brain is for having ideas, not storing them.
Have a calendar, todo list and a note taking app easily accessible so that when ever you have something that needs captured, it goes into that.
Make sure you capture anything that resonates with you.
Organize
PARA says that you have to organize by actionability. Put the information into the project that will need it.
Distill
Highlight important information. Use Progressive Summarization.
Express
Create content. Use the knowledge in some way. Ideally in a public way.
