I dont know how others do it but mine is simple. I am not addicted to gambling so I follow every rules diligently. Although sometimes we tend to be ignorance of some rules because of greed. Whenever I lose, am not happy I lost, but it does not get to me. Ill just forget about it because the money I lost was already forgotten the moment I decided to gamble. This is how every gambler should react towards losses.
Losing certainly won't come with a good feeling and most gamblers are not able to process such emotions because they are not mature enough mentally... It's normal to feel unhappy when you lose but just like you said, you don't allow those feelings to get to you... it's the responsibility of the gambler to suppress those negative emotions otherwise it can propel the gambler to start chasing losses.
No one feels happy enough when he gets a defeat either in large or small amounts. but of course as you said to avoid all things that are not desired and will only increase the losses experienced, then you must try to always accept the defeat that occurs. Always remember that defeat is part of the game.
These type of stories are more important than the ones people share about winning huge amounts of money, this is also a win. They usually say you would never win if you quit but it's the opposite actually, the day you quit you have won. You did something that a lot of people are currently finding it difficult to do. It takes a lot of efforts to curb irresponsible gambling, no matter how you little you think it is you made progress
To become a more responsible gambler, in addition to being able to learn from the mistakes we have experienced, we must also be able to learn from what other people have experienced, so that bad things do not happen to us in the future.
When we are still actively involved in gambling, the possibility of experiencing major losses and becoming addicted to gambling will always be there. Therefore, it is very important to apply limits in gambling, both regarding the amount of money spent or how long we spend gambling.
