You cannot work hard for gambling because it is assumed that if you are gambling more then your wins will not increase but you will face more difficulties as your bet can be true or false depending on your luck and there is nothing through accepting which you can learn about gambling.
Expecting to win more in gambling can actually be counterproductive. There, losses can be magnified more than wins. One gambler's luck will not be the same as another's so gambling by imitating someone will only increase the number of losses. Gamblers usually try to win quickly and those who lose in gambling also try to recover their losses quickly and want to ensure profits. But the results are not good there they lose more than gain. Over-expecting in gambling involves losing. Gamblers should focus on how to manage possible gambling without expecting too much from gambling.
