When you're already financially stress, you don't add another stress on top of that.
I would say that being in a state of financial stress not only adds an extra layer of pressure when it comes to gambling, but also leads to false hopes and unrealistic expectations. In this way, a person tries to compensate for failures in other areas of life. It’s a poor strategy, as it blurs the line of knowing when it’s time to stop. Even when someone does win, they often don’t cash out, because they’re fixated on a goal that is nearly impossible to achieve.
I have this principle of not gambling when I'm financially down, some people might consider such a phase the best time to gamble because they might get lucky. For me I see it as a very easy way to get desperate, you become more stressed out mentally when your expectations keeps crashing. Putting your last hope on gambling can be very frustrating, that's why I wouldn't advice anyone that's broke to do it. Most wins I have had where times that I wasn't broke, I didn't stress about losing the money in my account. There's something about gambling when you are not broke.
