Hi, i am wondering if anyone can help me out here. Been playing the game a long time. About 2 years ago I wanted to actually learn it and try get somewhat ok at it. I started fine, had a handful of lessons from well regarded coaches. I make a 39 about 18 months ago and havent come close to it again since. In practice I feel I can pot any ball on the table but break building is feeling impossible. I struggle to make 20+ in practice or matches. 10 red line up i cant even complete without breaking down. Feeling really disillusioned with the game at the moment. Feel my technique is ok, maybe I rush a little at times I dunno
