Thoughts come and go unless we jot them down. The paradox is when they came, I did not have a place to write. Bringing a book along most of the time is reasonable but not practical.

I usually have random, weird thoughts while I am in the bathroom, taking a bath, or sitting on the toilet. Yeah, the toilet. Recall wisdom I read in books. Think of problems I had last night.

I need to write them down. A book and a pen are in the bathroom.

It works pretty well so far. Once I captured my thoughts on paper, they were imprinted into my memory. Phone or electric device does not work. Paper and pen are classic. Work perfectly.
