This reminds of when I was in school and we had 3 categories of notebooks.

1. A "rough" notebook to jot down notes 2. A "classwork" notebook to present those notes properly to the teacher and get them corrected and 3. A "homework" notebook to finish homework assignments that used to be given

It's quite a discipline to jot things down in the rough work book and then write out a "neat" version in the class work book.

I stopped doing it once I finished school and realized I didn't really need to do it anymore once I understood what I was writing out. But maybe it’s a habit worth returning to.
