Ive won dozens & dozens of bets in the 10-15 years Ive been gambling. I dont keep a record but I have to admit I probably am at massive losses if I added it all up - Wins vs Losses.
Gambling is just a hobby to me though, I play with amounts I can afford to lose.
I don't know if I really won or loss of all the gambling games I played if I will put my games together all and my wins and losses I don't know how much I win and loss, but the most important is, I know that when at the point of being addicted to gambling, I've learned to stop and move on, on all of my losses.
If you know how to stop and move ahead on loss, then it means you are a mature gambler who know exactly how to react. Also it is important to know when to quit after winning because if you do not quit after winning and keep on playing and playing, you will end up losing the winning amount also. So its better to know how to play both in case of loss and a win.
