While not exactly the same thing, I do think there are overlaps with this.

I love annotating my books. I personally view them as a form of journaling. Writing out my thoughts, making highlighter marks, etc. It kind of takes time out of reading because of the patience it requires. I don’t read as fast because I’m making notations in them. Still, my books become a sort of journal because it’s similar. The only real difference is that I’m marking my thoughts with words already on a page.
