Gamble with the amount of money that you can afford to lose. If you can afford to lose $2000, then you can gamble with it. If you see gambling as a way of making money, that is the worst indiscipline that you have in gambling, never depend on gambling at all other than seeing it as fun and entertainment and not going beyond that.
I second with you not always what you have on your mind would be the same and could bring you good luck , gambling is hard and you can loose all your money for nothing in return . . mark my word and be careful and always think of plan B
