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.
This is indeed natural. however much we win will not give satisfaction. because we have greediness and we can be sure we can't enjoy gambling. for my example Usually when I get a victory is to use that money in accordance with my original purpose of gambling. usually I will buy new items for use or other needs. not so greedy in playing makes me not want too much big things in gambling games
