If your record is 37-27 and you are up only 4 units, you are obviously doing something wrong. You must be a guesser when it comes to how much to wager. If you keep varying your wagers, instead of making one amount for all, you are a loser. That shows that you do not trust your wagers. If you do not trust your wagers to the same degree, you should not be wagering. You also wager on every sport available, and that shows that you are an amateur.
