I can type incredibly fast -- 85 WPM on a good day. Then I see people typing 120+ WPM and I think, "Jesus, that's like the difference between me and someone who only types 40 WPM. How is that even possible? Maybe I can't type incredibly fast"
I can't really wrap my head around it being possible to increase my typing speed by 40 or 50 WPS. I think the world record is over 200 WPM. My fingers are already moving so quickly and fluidly when I'm typing at my fastest that it doesn't seem possible that they could be typing more than twice as fast. I guess I don't really know what my point is.
and so on . . .
