How to improve at basketball?

I'm looking for in depth info at how to get better at basketball. Drills, technique, floor strategies, anything. Ive been playing for 2 years and I'm at the point where I always play pick up but never win and I'm sick of it. Im slowly gaining confidence but I'm incredibly inconsistent. One day Ill be automatic with my jumper and the next ill be air balling everything. I've copied Kobe's form and always try to shoot like him.

Anyway to build confidence also? I guess just keep playing... but I'm just sick of losing :(.
