A gambler can have a hard time deciding when to stop gambling. If he is on a winning streak in gambling it is highly impossible for him to stop himself from gambling as I know from my experience. When a gambler is winning he feels more aggressive and desperate for extra earnings.
To deal with that particular situation he must have patience and refrain himself from gambling.
Without having a plan before we start gambling, it is going to make it difficult for us to control ourselves, some of us might say we can not be forced against our will but when you are winning continuously, you would not want to stop as you will consider that day to be your lucky day therefore you will continue to gamble and this might put you into problems as at a time, your luck will run out and you begin to lose then you switched from playing as you were enjoying the games to revenge. Revenge gambling can never give you anything positive therefore you will be fighting a lost battle that will eventually make you to lose all your money and get you depressed that it might lead to the start of your addiction problems. Having a specific bankroll prevents you from over gambling therefore it is very important.
