best way to spend your time as a new or not as adept player

learn what all the champions do and learn all of the roles. I like solo que, you are probably thinking why the hell is that? Well because i can play each role equally adept and hard carry from any lane. How stressful do you think it is going into a game feeling confident wherever im put either im last pick or first pick im satisfied with playing the role. I think that is one of the ways to get better and relieve stress as well. Apdo does so well because besides being a faker 2.0 he is a faker 2.0 at jungle, adc ,and top while faker is just mid lane.
