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.
The only thing you said that makes sense to me is that gamblers should not expect too much from gambling, everything else you said is doesn't make much sense, and a lot of vain repetitions as well.
I have said this over and over again that, it's absolutely wrong to use your own personal gambling experience as the general experience for everyone else, understand that; because you are losing, doesn't mean that every other gamblers out there are losing, so many people are winning, exactly same way so many people are losing, we should stop painting this picture of gambling that shows it to only be bad and no good side to it at all, this is pure deception and I personally disapprove it.
You are gambling and losing doesn't mean that there aren't people out there gambling and winning, share your personal experiences and don't generalize it, because your personal experiences is not the same as that of other people.
