Something that I can honestly thank League of Legends for
This game taught me how to type without looking at my keyboard. Seriously. My school didn't teach us how to type very well at all. We did maybe one or two units on some dumb "mavis beacon" program that was supposed to teach us how to type, but everyone just got through it by typing one finger at a time and looking at the keyboard. My parents never pushed me super hard to learn how to type properly, so I never really learned. Until I picked up league.
The I was forced to memorize where all the different keys were. Then I was forced to learn how to type quickly if I ever wanted to say anything in chat. Then, over time, I got better and better at it.
Without league, I seriously might still be typing at 20-30 WPM.
