This is taken from the book "Trading for a Living" by Alexander Elder:

Traders would benefit from our own self-help organization - I'd call it Losers Anonymous. Why not Traders Anonymous? Because a harsh name helps to focus attention on our self-destructive tendencies. After all, Alcoholics Anonymous do not call themselves Drinkers Anonymous. As long as you call yourself a loser, you can focus on avoiding losses... A trader has to admit he is a loser, just as a drunk has to admit that he is an alcoholic. Then he can begin his journey to recovery... This is why every morning before trading I sit in front of the quote screen in my office and say: "Good morning, my name is Alex, and I am a loser. I have it in me to do serious financial damage to my account."
