Another great one. I can’t remember if I asked you in a previous comment, but have you read, How To Take Smart Notes, by Dr. Sönke Ahrens?
This line reminds me of his work where he calls the process of taking smart notes as thinking on the page or external thinking.
If you haven’t, I think you’d enjoy it.
You make several very powerful observations and give some great advice here. I really like the theme of imagination as being the real driving force behind things. Creativity is the stuff of genius.
