So i have been primarily a sng player and i possibly want to learn cash in the future. However, i can't lose too much doing that as i need money to live. My bankroll is low so i have to play pretty low.

I can beat sng's but obviously there's room for improvement. I wanted to start committing more time to studying/playing less tables so i can improve my confidence but i'm not sure if there's any point if i'm not going to be playing the same games in 6 months. I might as well play a lot of tables for a lower roi then switch games.

I'm unsure whether thats the right decision though. How would you approach it?
