I agree with you because it is hard to determine when enough is enough because we feel that we can win more money if we continue to play. Maybe there are only a few people that can get out from the gambling places, and they can feel satisfied for anything the result that they can get in that day. We need to learn about enough is enough in the gambling game so we can control the emotion that will always be related in the gambling game.
I think the only target that you should have is to have a good time. Besides, we all know that you're going to lose in gambling plus we're all telling ourselves that we're not gambling for money but rather for enjoyment. The problem with having a target profit is that we keep on betting until it is reached. For most of us, it was never reached. In your first attempt of getting that profit target and losing instead, you're going to have more profit target the next time you go back. Then so on and so fourth. It's only when we realized that we've lost too much in hopes that we're getting that amount of money do we stop.
If we want to gamble, we set an amount that we can afford to lose and if that money is lost then you can stop now. Don't get your money that you lost. Just walk away and bond with your family and friends.
Gambling is actually a quick rich thing and not an activity for fun and entertainment. The thing though, you can quickly get rich from it but you have to be the luckiest person on Earth. Just what are the chances that it's you. It's also not fun and definitely not entertaining to see your money gone in just seconds of betting.
