Does anyone know why so many people lose at sports betting?

Quite simply, the vast majority of all gamblers maintain poor money management skills. That simple reason above all others is why they lose money. There are those that manage money poorly because they are uninformed and there are those that manage poorly because they are undisciplined.

If you are serious about success, it is imperative that you make a plan and remain disciplined. Your plan must entail proper bet size per unit or per game. You should never risk more than 1% of your bankroll especially not on underdogs.

It is imperative to bet a low percentage of bankroll to achieve success. If you are betting too high of bankroll percentage, one losing streak could eat up your entire bankroll and put you out of business. We cannot stress enough how important this concept is to your success.

Make a plan, establish a bankroll, stick to the plan and you will make money. Don't do those things and you will not.
