All my life when learning something new I've been taking notes (doesn't matter if paper or pc), specially when learning new technologies I use to write my own guides for myself to know exactly what steps I take and why.
I'm even concerned when I'm mentoring someone new and they don't take any notes or write anything, they just copy or do.
I've been told many times by different people that "they don't take notes", but I think noone can just learn by hearing/seeing, even by just doing. I think no matter at what point, you MUST take notes or write your own outline or w/e.
(This also applies for programming comments, of course).
What do you think?
