"I'm so dumb! I should have ended the game while I was
still one thousand dollars ahead."
There
seems to be a streak of indecisiveness and lack of self-confidence in your personality.
Before events you tend to be unrealistically hopeful, finding
potential
rewards hard to resist. After events, when your dream is not
realized, you quickly lose your enthusiasm, condemning youself
categorically over what has been little more than gamble to begin with.
