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.
Expectations is quite a huge barrier for most gamblers and they also face this troubles due to their lack of control. Having expectations on things we don't control is not meant to be so, due to the change of behavior when our expectations don't come through. Leveling things down to luck, is a general perspective from most gamblers. Since we don't own a single control over the outcomes of games, luck can be a better word for gamblers to use after winning a game. Because, the winner wasn't the only person to participate in the game. Even, sometimes, in games we are able to control, luck also plays a vital role. Moreover, hard working gamblers who don't care much about winning have nothing to do with luck. Building up a strong gambling strategy isn't about luck. It requires the dedication of the gambler.
