Never think about getting revenge for your losses because it won't always work but can cause you to suffer even more losses. You must realize that the mistakes you made that caused you to lose your chance to win happened because of your unintentionally. So you think about trying to recover your losses but think you are gambling just for fun, and with money, you can afford to lose. But if it's big money we accidentally lost at gambling, we shouldn't regret it because it happened. And it's best that we can be more careful on another day and always check everything before we gamble.
Well, revenge is a strong word so I am with you on that but if the case of trying to win back or breaking even on your losses, I think that it depends on the amount of loss that you've got, if you think you can get back the losses by winning big with such a small amount of bet difference then go for it. I don't think it should come to a time where you're regretting your expenses on gambling, you're an adult now I am sure that you know what you're doing when you are gambling, regretting just leads to you being psychologically set to try and ease that regret by trying to gamble again.
