Don't bet what you can't afford to lose - This is generally known as the golden rule of sports betting and is one thing you absolutely don't want to do because you'll hit a cold streak sooner or later and lose all of your rent money.

Use proper bankroll management - It's essential use proper bankroll management because betting sports can be very streaky. Even professional bettors can lose 9 or lottery 10 games in a row and in case you are betting too much per game you go bust. Think of your bankroll like your child and do whatever it is important to protect it.

Do not bet too many games - You know when Sunday comes and there is 15 NFL games you do not have to bet all of them, you only want to bet the games you have an edge on and most successful bettors will only be able to find 2 or 3 games that they have an edge on.
