If you don't have a positive mental attitude or PMA about winning, regardless of the specific game involved, don't play. Don't get in the game if you don't feel good about it; lay off for that day or session. If you're in the wrong mood, gamble another time. Subconsciously your focus on the game, your concentration and reflexes to the changing action will all be affected and it will show up as a low win-rate. We have all heard the song, "Save it for a rainy day." if necessary, do the same when it comes to casino gaming. Save it for the next time if your PMA is not right.
