Honestly, the first thing that came into my mind when I was winning was to play and win again until I earn more which lead me to losses. I almost forgot all the risks of gambling and that there's no guarantee that I could win all the time no matter what my strategy is. From then on, I have set a target goal so I would know when to stop.
Indeed, begin to understand that no matter how good and cool a strategy you have will not be able to make you win in gambling all the time. That means you won't always win every day, so from now on when you win, withdraw it and use the initial capital again to play in the next day. Winning every day is impossible, but winning more often, and losing less, I think thats possible?
I'm sure the mindset and plan can make you stop playing when you win.
