re: Poker & BRM and Discipline HELP!!!
Whenever you are on a downswing, instead of trying to move up and make back losses (which never works because you are on tilt and are trying to "make things happen"), just stop playing. And start studying.
If you have tracking software (recommended, but not necessary) go through your hands from the previous session. Winners and losers. Ask yourself questions as to why you made certain actions and be honest with yourself about your reasoning.
Also, take some time to go over threads here on CC. You'd be amazed on what you pick up even just by scanning over strat threads.
I'd recommend a 60/40 split between playing and study for a while until you get yourself back on an even keel. Myself and many other competent players devote at least a few hours a week, if not more, to purely analysis and study.
So next time you hit a downswing, either due to variance or poor play, just STOP PLAYING and start study. You'll cool down and when you do get back into play, you'll be a better player and the wins will come back.
