I used to be afraid to play and lose a bankroll, but now it happens to me as a player muse713 - As soon as I started to strictly manage a bankroll, I realized that there was no more fear. This allowed me to take risks and play with confidence. I'm still a little worried if I take a shot at a higher limit. But for the most part I can say that I am a confident poker player.
i agree with uTry to control your bankroll, the bigger the bankroll, the less fear.
