Goals
Many people have wrote that setting goals is an important part of becoming a winning player. I am not so sure. I have never set a monetary goal for myself, and I feel like the inherent variance in poker make those kind of goals non-productive. Is it better for your long term game, if u repeatedly get your money in behind, but luck your way to a tourney win, or if you routinely get in as a favorite, but happen to lose money. Clearly, the latter is a better strategy, yet having a monetary goal will lead one to the wrong conclusion.
I try to be decision oriented rather than results oriented when it comes to evaluating my play and setting goals. My only goal for 2006 was to play my "A" game 80%+ of the time.
Another thing, what is the point of a goal? The bottom line is that at the end of every session, you will have issues to consider regardless of the outcome. By working on those issues, thinking them through, and trying to figure out the optimal move, you will become a better player. Meeting your monetary goal might just be enough to convince you that you are above this process, and that cannot be a good thing.
