at University I would copy all the notes I took, which were poorly written and confused, into nice hand-written notes with charts, plots and formulas. That was for all the courses, for 7 years.

Alas, I am not doing it very much nowadays, but that's also because my learning is much less structured and much more "operational" (I need to learn this in order to do that). Edit: typos
