I did this. Left a cushy corp job a few years ago, then worked on my own startup for 3 years. While we had some small funding, we could only pay ourselves very little salary (almost below livable standards for bay area, cutting into savings a little monthly), and in the end it had to shut down after 3 years. Went back to regular job (non-corp, an early-mid stage startup) after that. I think the only factor that I have regrets about was financially. Not so much about having to cut into savings because I had good enough cushions anyway, but just realizing that I could've had 3 more years of high pay and stocks and padding the investment account with more money, and putting myself 3 more years away from retirement (or maybe more considering compound etc). Other than that, entrepreneurship was an awesome experience that I wouldn't trade for anything else really.
