Every responsible gambler should have a gambling limit and he should stick to those limits no matter how tensed the game might be or what turn the game takes, it's always crucial for gamblers to stick to their limits, and if for any reason, you happen to have exhausted your limit, the best thing to do is simply walk away from the casino and come back next time and not exceed your limits.
A gambler should have self control and always gamble with a levelled head, never allowing your emotions substitute your brains and start making decisions for you, cos when that happens, you'll start making illogical and uncalculated decisions which often leads most gamblers to their doom, it's important to avoid these things before they even happen.
I think what you are suggesting is something that is quite worthy of consideration because gambling with a calmer state of mind and not controlled by emotions will feel more enjoyable and also more relaxed in facing each game even though this will not guarantee a win. But by setting the limits you mean, a gambler has also won in fighting his emotions because the most difficult thing in life is fighting the emotions within ourselves against the attraction of something we like. So taking into account what you say is quite natural and not wrong for all gamblers.
I think you really do understand the point I'm trying to make.
Gambling shouldn't always end in regrets or unimaginable losses, yeah gambling is game of luck and chances, so the chances of losses and wins are there, but a gambler should always acknowledge the fact that the odds are mostly stacked up against them thereby making the chances of losses way more higher than that of winning.
By acknowledging these facts, a gambler can be able to teach himself not to stress the wins too much, because stressing the wins too much could amount to more losses, so just have a budget, if you're able to win before exhausting your budget, good for you but if you're not able to make a good win, then there's no point stressing the situation further, just accept the defeat and walk away rather than trying harder to win.
Gambling doesn't work that way, if luck isn't on your side, then take a chill pill and just accept defeat, and know that another day could be your day but not just that day because you cant always wim in gambling. Knowing all these could really help to eliminate the risks of more losses in gambling.
