I am in the same boat. This year I will turn 35 and have not yet started anything. I think fear has something to do with it and the other is finding the technical talent to help bring ideas to fruition. I am pretty sure that having had work experience will definitely be beneficial.
As far as having a family to support goes, I have 2 kids and I am pretty sure I can't leave my job even though my wife works. That just means I would have to do something part time, which in the end may be better. I read an article where an entrepreneur spoke about the fact that founders will put a lot of energy into their startup and not develop a balanced life from the outset. That only puts you in a mode where work will always consume a lot of your time and you will not be able to break that cycle. At least if you work 2 jobs for a short period of time, you know at some point you will quit one of them.
