I have a very big leak, thats costing me at least a buyin for every session I play: I call too much postflop, instead of folding when its clear that I'm beat or/and when I'm facing a big river bet with a very marginal hand. I need to fold a lot more postflop, because I'm bleeding money right now and it hurts my winrate a lot - also because this leak easily leads to tilt. But I cant seem to plug this leak, I continue to be a calling station. I need some advice from you my fellow brothers, what do I do? Make a thread where I post all the bad calls I make? Write "FOLD MORE AND CALL LESS" on a piece of paper a hundred times? Any ideas?
