6. Ignore personal bias
Most people who bet on sports enjoy watching the games that they love as well as like to see the teams and players perform well, which can influence their choices.
Although it's not a major issue when it comes to backing your favorite team, but it's important to avoid allowing personal biases to affect your decisions in gambling, for example, the team you support is playing against another team, and you are very sure that that other team is going to win the game because they have a very much stronger and well coordinated players than your favorite team.
What are you going to do?
Betting on your favorite team even though predictably you will lose is not wrong even though many bettors still bet on teams that are not favored because of other factors such as match history, many good players on the opposing team do not play (if this is a team game) or the type of field that is not the preference of the favored player (in tennis for example) and you know that the odds given to the underdog team or player are very tempting and the theory is the same we do not necessarily win when betting on the favorite team then betting on a weak team does not guarantee defeat, because there are many bettors prefer to take high risks.
7. Keep Records of Your BettingMost people who start betting on sports fail to keep records of their spending. This is a mistake, as it can be very hard to track how much money is being spent, Having records will allow you to monitor your spending and improve your strategy and odds which in turn increases you chances of making a profit while you bet/gamble.
you have to be disciplined to be able to do this, but if you are lazy to write down all your bets you can do it by betting only on one bookmaker there you will be able to see your betting history and the final balance minus the deposit you will know you are profit or are experiencing a loss.
