That will be a never ending emotions, when we gamble we should always think fresh and forget our previous losses, that more we chase are looses the more we lose.
That is why I could say that gambling is one good test for a persons character,how he handle his emotions.If temper/emotions left unchecked you cant focus on your games,but instead going after a win always.Concentration is destroyed,and eventually you are correct,will lead to losses.
