Budget: set it BEFORE you start gambling and stick to it.
Also that the budget on gambling weekly should not be higher than 2 to 5% of the gambler weekly income.
Have a break from time to time, it is important to let your brain stop and consider.
Gambling should be for fun. It should not be what someone should consider to give a break for, but to be done at a very short period of time weekly.
Gamblers should not chase losses too
Do not stress yourself trying to win over gambling. That will not happen as gambling will always have an edge over its players. And always remember that gambling is designed for solely entertainment, and not a get rich quick or an avenue to give you fixed amount of profits. So never be fooled in gambling, learn to control yourself and just gamble on the amount you can afford to lose.
