That is the problem with us when we are winning. We think we are unbeatable and all our bet will be correct. So instead of stopping we tend to bet more only to find out at the end that we have emptied our bankroll. Gambling is profitable in the long run if we know how to quit and continue the games the next day. If we failed to know this, gambling will never be profitable.
This happens when success gets into our head and we think that we will keep winning always which most likely is not happening and may be at the end you may go empty handed due to the loss suffered in gambling . So always when you win just take the money and go away .
