that be positive always, when you start gambling or what ever you do just stay positive because negative think don't do things good, but in the world of gambling there is always a situation sometimes you win, somtimes you lose. vice versa. That's why others said Gambling is a game of luck. The important is you enjoyed every game you start & untill the end of the game.
For me the positive attitude on gambling won't always bring you a good result. That is why most gamblers don't stop their habit because they always think positively that they will win in the end. Sometimes in life we should accept the harsh reality. We can't be a successful without working hard not just depend on gambling.
