My tip to improve your typing speed is to...keep going until you get faster, and if you aren't getting faster, then you aren't doing it right.

When my fingers hurt after too much time on the keyboard, I...keep typing until my finger are so fatigued that I have to stop, and then I take a break for a couple of hours and then get back on the keyboard.

I mean that's why I play online videogames..

What really helped me improve my typing speed is...playing multiplayer video games, and my mechanical keyboard. It's a Blackwidow ultimate 2014
