It's only unsatisfied gamblers that are permitted to feel that way.I've been able to groom myself to a point that I don't get to feel less of myself from gambling or feel pressured over several games outcomes.
Once you let yourself to feel less as if you're not doing enough,then there's no guarantee that you're taking the best decision for yourself.A responsible gambler should be aware that a feeling of nemesis shouldn't be accommodated during that period.
Sometimes it's not about doing enough or not being satisfied with the game result, but about not being able to accept failure, and once you see your game near winning like that, you can be tempted to try again. I don't consider that as being unsatisfied, but if you are also okay and cool and have self-control, you don't try again after losing such a close game. That's also a good thing, but some people can try again but know no limit to when to stop.
