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.
