Hey craftsman, though I think you should quit too, but asking for such advice on HN you'll most definitely get a biased view - because everybody here is so passionate about what they do, not how much money they get paid! right?

I think there's absolutely nothing wrong with a person happily living with a corporate life. But if you are growingly sick and tired of it, then what's the point? From the sounds of it you do have a pretty successful corporate career, so I doubt it'll be hard for you to jump back into it.

If you are scared of the possibility of failure, fail faster (which reduces your opportunity cost), and fail spectacularly!
