C: Remove the mindset that gambling will make you rich overnight; of course many people have made huge fortune from gambling but do you know how much these people spent to win such huge profit? Bet with what you can afford to lose and also bet according to your capacity.
Gambling not only can't make you rich overnight, but it can't make you rich either. If you see someone who can win a life-changing amount, it doesn't mean that all gamblers will experience it, the percentage that can get it is very small. If you want to gamble, gamble normally, not because you want to get rich, because you will be disappointed and become unable to control yourself, and never be tempted by what other gamblers get, because winning at gambling is not like improving skills where other people can do it and you can too.
