"With kids it would have been impossible."

It's not impossible, it's just adding another degree of difficulty. I did exactly this in the second half of my twenties. Working on my projects, doing consulting when I had to to support myself and my family. I believe the impetus that drives "family men" to seek shelter in a "normal" job can also drive you to be relentless in making your startup work. More skin in the game.

Also, team comes into play here. Personally. I know that if I wouldn't have had such a wonderful and supporting partner at home, the startup issue would have been a non-starter.

Team first =)
