I have a family also.. Y'all will think I'm totally nuts, but I'm a polyphasic sleeper ( http://en.wikipedia.org/wiki/Polyphasic_sleep ). Altogether I sleep about 2.5 hours a day, which means I can have a 15 hour work day (at night) and still have 6+ hours at just the right times to be with my family and do personal things etc. I have my wife's 100% support though, and that makes all the difference (I won the support by cleaning the kitchen at night, of course).
In some ways I miss the freedom of being a little younger and single- being able to drop absolutely everything and move somewhere, knowing you'll be able to take care of yourself at the very least no matter what. On the other hand, there's a certain stability in your life that comes from being married and from having children. It can really be an anchor when times are difficult. It also usually forces you to take a lot more realistic view of your potential startup. Will this really produce revenue? Am I really covering my bases? etc.
