I've read quite a few threads about self-control, budget management, and more in this forum. The content in these threads is indeed helpful for newcomers, but it seems like there are already too many threads like this here. Honestly, it makes me bored.
Many people tend to lose control when they experience big wins or losses. Yeah... the emotions from the mind usually influence them to become greedy or vengeful. Any limits won't be of any use, so it's basically nonsense for people like them.
Wise individuals will stay wise in gambling, and that's an advantage not many people possess. Without you teaching them to set limits, they're already doing it automatically.
We need to set a clear expectation that when it comes to gambling one person's gain is another person's loss and vice versa this we cannot plan much here when it comes to tactics but yeah the only thing which we control over here is the amount of isk which we want to take as it should only be the amount we can afford to use and if we win there should be a percentage which should be reinvested rest should be saved if we can create an strategy around it then we can conquer the emotions and act like machine.
I don't know if you have actually tried this plan of yours yourself because if you ask me saving gambling money is really likewise also reinvesting a little portion of it so what I do is I just withdraw my winnings and use it for something tangible that I won't regret spending it on and just continue with my gambling whenever I feel like as I don't even gamble on a daily, the habits comes now whenever I feel like it and not like before when it almost turned out to be an urge problem.
