I have a fine job, corporate, amazing pay, but my life is miserable. I come into work every day unmotivated to write Java, or work on the product we are building. I don't even spend the money because I don't know what I need it for. I even still live with my parents because I have no desire to move out (I'm in my 20s). Meanwhile, at the office, I read sites like HN and see startups left and right and feel completely left out.

In my perfect world I would just quit, and spend my days building ruby/comet/js/etc., all the cool stuff, and leave this Java world behind. I already have a knack for it, and want to just try the startup world, but every time I am about to quit, I realize I will have no reliable source of income, and once you get used to that paycheck you really get used to it.

I'm wondering if anyone has success stories, or motivational tips in general or have made the same plunge and do not regret a second of it. What pushed you over the edge?
