Says who? You can win with your high level of emotions, because losing and winning when gambling depends on luck, not your emotions, so someone who is emotional when gambling can win if its time for them to get lucky.
Exactly the same point as what I said before in this thread. The ability to control emotions is good to minimize the possible bad effect of gambling but it will not help us to have bigger chance to make money from gambling. There is no guarantee in gambling, whoever we are, how patient we are, how good our emotion control, how good our bankroll because Luck does not care about all these things. No body knows when the luck come, to whom the luck come, and how the luck come because it is like a mystery that we will never able to predict.
When one is playing gambling with emotion and trying to win the game, at this state of point it is impossible for the person to be able to think well. Playing with emotion is very dangerous and risky because with this state of mind thier is high probability for the person to lose it and after loosing their will be much regret and pain. I don't see reason why one would want to play gambling pressure and emotions when their is a high tendency of losing. I think gamblers needs to think first before carrying out any game especially when their is high emotions, because it is very to easy in times like this.
