StarCraft taught me how to type, gotta type fast if you're going to trash-talk on Battle.Net
One of the best things I ever did for myself. If you’re reading this and you don’t touch-type, learn. Now.
(They kicked me out eventually, so nothing good came of the copying.)
I remember briefly learning to type from a Mavis Beacon book but practicing on those clicker mechanical keyboards drove my parents nuts!
No one I knew could type, so I had to learn myself. By the time it was taught in HS, my habits and muscle memory weren't having it. I could type 'properly' but far slower, so I gave up.
To this day I've never had a RSI from typing (and some of the marathons were crazy!), and it's rampant among 'proper' typers.
