The typing thing for me for sure! I never understood what even was the point of having the "correct" and official way to type -- like I type faster all "wrong" than most people who do it like they're supposed to. I learned typing on my own by trial and error and like my style waaaaay better!
The point is that we never look at our keyboards while typing.
Oh but I really don't have the right typing technique, but I don't look at my keyboard ever, and am a pretty fast typist (90-95 WPM, 4-5% error rate according to this site). I know I definitely could be a lot faster and make a lot less mistakes with the right technique though!
Are all your fingers on the keyboard? Then it doesn't matter which technique you use.
Yeah they are, indeed.
I never look at my keyboard either it's all muscle memory. :)
