Most of the gamblers are not succeeded in gambling because they do not play gambling with limit, they play with everything they have, even if they will make a lot of money but still they are not going to stop it for the time, they try to make more and more money from gambling which in last cause a big lost and nothing else.
I agree with you and this is a mistake that we did in gambling games and we should be aware to not make the same mistake. it is better to make a limit in the gambling game so we can avoid getting loss all of our money and we can leave the place with the money insides our pocket. maybe we can try our luck in the other day and who knows we can win the games with easily.
People some time even know that they are making a mistake, but they continue and repeat the mistake again and again. In fact once they become addicted in gambling, then they find it too much difficult to get control over their emotion and which is in fact the big cause of losing money in gambling.
