Self-control? is the characteristic of most gamblers and they struggle to get rid of it. That's why there are so many gambling addicts because they don't have this quality. I know very few people who can do something like this. The second is the perseverance in maintaining Self-control because others only manage to control themselves at the beginning, then, in the end, they also give in and lose control, so the result, in the end, is still a loss, or money which turned into stone.
Self-control is a choice as it's a psychological thing that needs the determination to possess. It is truly a characteristic, a positive one at that, and no player that possesses it would be going astray against their will and their playing plans. Those people you know lack self-control because it is not about what they say, you should know through their playing character.
And as you know the ones that are addicted, I know too, but I also know those gamblers that are disciplined and not being controlled by the game, which includes me.
Self control is a character and it is a virtue, it is not learnt or it's hardly learnt at old age. It is better instilled at younger age of someone and the person grows with it. Self control helps one to solve many problems, including not over spending, over drinking or over gambling. It helps one not to plung into addiction. Once you have self control, you have solved more than 50% of your problems as a man. It is contentment that brings about self control.
