My tip to improve your typing speed is to...practice.
Because practically practice makes better. There's no shortcut, just long long way ahead of you. I mean typing stufff

When my fingers hurt after too much time on the keyboard, I...tend to like dance little bit, can't really call it a dance since I am just like posing some ninja moves for a couple of seconds then BOOOM! Back to business.

What really helped me improve my typing speed is... basically typing all those words. At first I was reluctant with this site since I wasn't familiar with this yet after taking some typing tests made me realize it wasn't bad after all. I do enjoy this a lot. mooiiiseeeth

When my fingers hurt after too much time on the keyboard, I... would usually take my time twisting it hahahah which is pretty much a joke. so yeah. ngaranga
