On long run gamblers can't beat the house. Even if that gambler went home with 8000$ and didn't come back on the next hour or day to lose everything he would have lost it along his future gambling sessions. What he could have done was to use this money better through a proper management, so he could play for more time and have more entertainment with that same sum of money, instead of wasting everything on next hour after he has hit the prize. I believe he got too excited for winning such money and wasn't able to control his emotions. Let's hope this situation was useful as learnship for him.
^ As they said, the more you spend time gambling the bigger your chances of losing your money, and I think that is true.
That is why if I won on that session, I enjoy winning so that I feel worth it that I have won and come back when you are ready to gamble. Because if you come back hoping that you will make more profit, greediness will lead your way that makes your luck go away.
Never follow your greed.
