This is where many gamblers actually go wrong. They know they should control their emotions properly but they don't do it in their actual gambling. That is because they can't remove the greed and addiction from their character in reality.
But if they start doing this little by little even by limiting our gambling money, we won't notice that we will gradually be able to control ourselves.
Most of us do not realize when playing in gambling we are in a state of not being able to control emotions, maybe because of defeat or whatever it is, we will realize it when the game is over and we know it ends with an accumulation of defeat, that's when we just realize it and regret it.
It is indeed very difficult when talking about emotional control, such as when winning in the game we tend to continue playing because of curiosity and greed to win more, on the other hand when we lose we tend to get upset and emotions that can cause us to make another deposit just because we want to restore the previous defeat.
This is quite complicated, even if we already have an allocation in gambling, we can still use savings and even borrow when we lose, this happens because we cannot control our emotions.
