Smart bettors know not to play anything more than they can afford to lose. Betting the rent or grocery money always is a stupid idea, no matter how much of a lock a pick supposedly might be. When starting out, it helps to have a small bankroll of money that you can afford to lose, because if you are just learning, you likely will make mistakes. But, if you wager wisely, you won’t risk your entire bankroll. Professional bettors know the idea is to manage money. That means making your bankroll grow, even if only by a little bit, and limit the potential loss on days when luck runs against you. When you have those lucky days where nearly every pick hits, your bankroll will grow fast. On those unlucky days when nearly anything that can go wrong does, the amount you lose will be relatively small and leave you with plenty of money and time to wipe out the loss and still finish ahead for the week, month or year.
