Actually, I was just curious about other people's experience, especially in the worst case scenario (start up fails). Since I quit my day job to free my mind totally for entrepreneurial experience.

As for me I had a side project, geo-social planning tool, that had 5000 users, but not actively using the app. I shut it down, because it was unlikely to succeed, it was strange to the way people meet and go out. And also, because I noticed that other similar projects were also stuck in the chicken and egg problem.
