I really think there's something magical about beginners typing in whole projects by hand (instead of the modern copy-paste). It really helped me when I was getting started with programming.

To me, it feels like typing each character manually cements the knowledge in there much deeper than 'oh, I think I understand what I'm copy/pasting.'

Maybe that's a shallow truism by now, but I still see people struggling to learn programming via copy/paste from examples.
