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.
Same thing implies here. I have to lose lots of money not minding my level of finance. When i decided to stop was when i couldn't pay my tuition fees for a year which was given to me by my parent. I have used that money in gambling and lost all of it. It took me to work while schooling to be able to realize that money back. Ever since that day i have pay attention to instruction and gambling advice both from professionals and intermediate who have had lots of experiences.
