I'd try switching the game up. I noticed I've been getting bored in MTT mainly. I feel like if I bust out but I played the right 5-10 hands and things just went badly for me, then it was a success.
But I've been enjoying 10 man sit and gos, figure out the fish, get their stack or survive to gamble once, and then play real poker 4+ handed.
Been working out pretty good for me.
But definitely respect the BRM, ESPECIALLY when you're running bad. I'd try switching the game and do 10 of the lowest Sit and gos you can. If you loose review your hands, check the odds
, make sure every decision was right. When you start winning then move up.
You can do the same with MTT's too, but I think moving to a shorter game should help, and I think it'll lower the variance.
