I want to be good at this game with a proper guidance over my gameplay.

Hi. My name is Yushan Bhattarai and I am from Kathmandu, Nepal. I've been playing this game for nearly two years now but due to some boundaries over my house and my studies I am not been able to play the game. I have a group of friends who play with me for fun not for full gaming. I am willing to improve but I ain't getting any chances to improve or proper guidance for it. It would be nice of you guys if you could guide me through ??.
