ok so ive been playing for about 8months now. (self taught) im happy with my playing and happy with the compliments i get on my playing. but im pretty sure there are things i should be doing, that im not. so..

...i was just wondering what are some of the main things you want to be able to do on guitar and what to be practicing.

i just want to be decent and respectful when it comes to playing with / around other guitar players.
