I want to quit my day job and do indie games full time. However, I don't make enough money doing just games. Has anyone been able to live comfortably without working and doing games full time?

How much money do u generate?

Yes, of course. Many indies make a full time living this way. But how much you make is up to you. Some make less than $100 per month, while others make well beyond $10,000 per month.
