In my case, I have to lose a lot of money to realize I have to gamble responsibly if I don't want to break my finances and experience depression, so now I control myself and monitor my expenses, and I'm doing good with it.
This is exactly what makes gamblers begin to stake responsibly after series of losses but it is also same for gambling addiction because some gamblers when they have lost a lot to gambling they try every means to recover and keeps losing till they become irresponsible and not able to control their gambling life anymore. Normally, even in a business when the business is not experiencing growth the business owner either shut down the business or plan to open a new business so it is in gambling because on a norm no body wants to continue losing money so a situation where you are able to realize when you are going out of the box you should know that is the time to start being more disciplined and responsible. Knowing when to become responsible in gambling is good because it also help you to know you are taking your gambling to a bad direction so it will make you to also restrategize on how to win or to move to other games you can be familiar with, possibly you may prefer the game better than the initial one that causes you too many losses.
