I think greed is a trait shared by all gamblers. I'm sure all gamblers have had such experiences and we should learn from them. Often when we place a bet with a small amount it turns out it goes according to plan and when we increase the bet it turns out we lose and all that is left is regret.

Sometimes I make targets, how many winning targets I want to achieve. If the target has been met I will withdraw all or part of the money. Then I will play the remaining money that I have withdrawn so that when loses comes I don't lose my capital
