1. put your fingers on home row keys with pointer fingers feeling the bumps on F and J
2. DONT move your wrists all around, try to keep them still and let your fingers do all the work. try to keep your entire palms as still as possible, they really shouldnt move. I rest mine on my laptop surface.
3. dont look at the keys. use https://www.typing.com to help you if you cant do that
4. relax your hands as much as possible
Typing.com is better IMO if you don't know how to type fast, and monkeytype.com is way more fun when you do (the interface is just way more fun)
