Writing down your chess ideas

A serious member here in the chess.com community suggested that I write down my ideas when analyzing any position. I tried to put this into practice while solving a position from Yusupov's book. I actually found that my thoughts became less chaotic and more to the point when writing down the ideas I had. I actually scored higher too on the puzzles.

I am now thinking of writing down entire games and my analysis of the games in a notebook.

Has anybody else put such things into practice?

Doing written analysis has great value but I don't see much extra value to be gained by having it handwritten in a notebook. Annotating a pgn file makes it accessible for future use.

It is actually my coach's idea. He writes extensively including long paragraphs of instructional material such as the why and when to make positional sacrifices etc.

It is very useful to write down and analyze your real games or your ideas. I use this notebook: https://www.amazon.com/dp/1723829463

It is very simple and easy to write and read.

Cool. My coach also used to have stamps for pieces and stuff so he could imprint diagrams in his notebook. I thought that was really cool.
