Yes, we have to be careful with the games that we're betting for. Because if you can afford to lose the amount that you are betting for, that's fine if you do it with caution. But not everyone can be on that state as they bet, they're letting their emotions do things on their own. And for those that are continuing to gamble that way, they're dragging themselves to the pit for them to fall and will hardly recover later. It's simple if you've been in the hardest times because you'll be careful with yourself and the bankroll you're setting.
There are at least two types of careless people in this case. Those that can afford to lose the money and dismiss it as not important, when it is important. Also those that get very upset at losing the money, which can trigger them to chase and try to recover it.
I guess that we've got our own triggering factors whenever we gamble. It happens to most of us but after doing that, we're calmer and realizing that it's a mistake that we shouldn't do anymore. Those that can afford to lose money, they have a lot of it pack to their bags and that's why it is easy for them to lose it. Whilst the typical gamblers, they know when it is good to give up and when they have nothing left anymore because of their recklessness that needs to change whenever they are up to gamble.
