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.
When I am winning in the gambling or gamble sessions I already just have a goal on winning on what is the exact amount of I will win. If I win I just continue the betting game as long as I can get my goal or exact amount I really need, but there is also a limit that I can lose and if I ever meet my limit of losses I will stop on gambling or playing. The things that really comes to my mind when I am winning is the limit of my needs or the exact amount that I really want to get in this game.
