I would say that just keep things balance. Because when we're so emotional and we're not controlling it, worse things could happen to us and our money.
It's no longer a theory when we don't control our emotions. And for that reason, we have to make ourselves in the right state when we gamble.
Yes, we can have fun and have some little happiness but there should be still a limitation to that so that we won't be too much to ourselves and effects of it.
