Your thinking that what will happen if you lose signifies that mostly you play the gambling for money and not for fun or entertainment. If you play for fun than you would enjoy the while process rather than waiting for its result and thinking negative. Become part of this and see the difference yourself while playing.
I agree with this, there is two types of gambler. One plays for just pure entertainment and the other plays for merely profit. The two have a different mindset but both expected to win. The first player doesnt have a pressure whether where his luck will take him because he has something or a particular amount of money he can afford to lose. The second one always put a pressure on his mind in every bet because if tbe bet lose, he will lose that money and can never get it back.
