You need to figure out if you are playing well or not. Go over your
hands and study. I don't really believe in running good or running bad. What does that mean, anyway? It certainly has nothing to do with any future play unless you let it. Cards are random; if you play well, you will win in the long run. It doesn't matter if bad players beat you sometimes. If it's all the time, then I think you need to worry about your own game.
Be happy if you have the best of it and someone sucks out on you. You played well. That's what matters, not the short-term results. If you dwell on the idea that you're currently being lucky or unlucky, it will affect your play negatively.
