You will certainly have more bad days than good days. There is no point in going on some kind of rage and blaming everything, it is counter productive, it probably says more about there character in general, rather than the game itself. If people cannot handle it mentally, then maybe poker is not for them. I find those that complain about how much it is rigged, or it always happens to them, bad luck, are just lazy players, they gamble too much and have no interest in analysing there game, look at there own mistakes and never study. Sometimes it is best after bad sessions or a run of bad luck, it to simply take a break, use that time to do something else, fresh air works. Also using that time to study, recognize the weaknesses in your game, study and look to improve those weaknesses.
