there is no "streak", it's about playing correctly in every situation over and over, and ignoring results.
Most players are so results oriented it's ridiculous, you can not expect to win hordes of cash every time you sit down in a game or tournament. It's just not going to happen.
Soupie made a great post a few months ago saying if you play for money, you should probably just quit, because it's not easy in the long run. It's not motivating, but it's very realistic.
