The problem problem comes from greediness , desire for more after some wins .
Well, it's okay to desire for more but you have your profit already and still want more and more , IMO there should be some return target profit according to the fund use for gambling and once its acquired you could pause it to play next time or you could use out of your extra profit gained from it if you desire for more and if the opposite comes set a point to pause gambling (for loss), with these you can make something out of gambling nor gambling it all with focus ,besides gambling should be taken as playing for fun
Trying to chase loss is one of the easiest way of Lossing all you have left. The major fact about gambling is that, what is gone is gone. Just forget about the past and move on, that the only way you can gamble without putting too much of pressure to make sure you win a bet, is when you forget about the past and focus on the future. If you win consider it luck for the day and be excited for it rather than thinking of past loss.
