I stop gambling when I lost all my money. I start again when I have money.

It's that easy. No seriously, if you don't have money how can you gamble? When you make money from your regular job you can start again. It's a passion, it's a lifestyle. You can't quit when your life is gambling.
nah yeah when you consider gambling as part of your life your habits your needs then you will never stop it , just like you consider eat as your needs , without eat you might die lol. as long as gamble didn't affect something really bad to your daily life , it's okay to gamble continuously.
Well when you're that addicted to gambling, it would definitely take a huge amount of your time that you'd be better off spending a lot more important things like your family. I don't think it's that simple that because it's your passion, you'd consider it as a necessity. A lot more can get affected when you come to that point not just time and money
