Those stories are never heard because they never happen eventually the end is usually a loss for the gambler. You can't beat the house by going aggressive on them you can only win them by lucky. When our threshold is reached after many sessions the best decision is quitting and not redepositing in the hopes that you might get a recovery of your loss. Internalising a high level of discipline can be helpful is restraining from yeildiing to the urge of gambling aggressively.
I think the problem most of the gamblers when they are winnings is, what is the right amount to stop once winning, usually they didn't notice that they are losing already after winning an amount. It's either they are getting greedier or unable to tell when is the good amount to stop, usually when I notice that I am winning, I will withdraw my 85-90% of all my total money from the site and I will leave the remaining 10-15% to play with, so if that made me earn more, the better but if I ended up losing, then I already managed to secure my profit.
