The case in gambling, you might feel different emotion as you gamble since it's not always positive, losing are more possible to happen. Emotion can take you to many places, so always look for the bright side and commit with your strategy and limit, don't over budget and gamble because of your too much emotion, self-control is still advisable at any situation, forget that emotion when you are already losing to avoid any risk and losses.
Totally agree with your opinion, it's true that we will definitely be faced with all emotions when gambling.
We also have to be able to control ourselves so as not to be consumed by the negative side of gambling.
Maybe only a few people are wise in gambling and can control themselves.
Sometimes most people in the end cannot control themselves when gambling because they hope to win big.
There have been many cases that prove that when they gamble, they will sink into their addiction and will always end up causing problems.
The strange thing is that before gambling we know that emotion can destroy our game and money. Also we read often how emotions in gambling can make you lose and we are confident that other gamblers can't control their emotions while we will have no issues.
But as soon as we started to gamble, we do not realize the emotion overcomes us and due to that, we may spend more money on gambling, on losing we try to cover the losses, and on winning we become greedy and keep on playing. All of these things are because we are unable to control our emotions just like ordinary gambler.
