If you follow bankroll management, you can rest easy that regardless of how badly fortune is treating you, a) you're being sensible about it and b) you're not going to go broke*. If you don't, there is a good danger you WILL go broke AND it will be entirely your own fault. It's a pretty easy choice to make

*NB there is a tiny chance you might go broke in terms of the money you are prepared to lose, but you won't go broke beyond that because frankly, if you do manage to go broke despite the necessary drops in levels as your bankroll shrinks, you're obviously not a good enough player to win at poker, variance or no variance
