Women lurv engineers, there has always been great engineering by married men. The great discoverys come 'out of the blue' by someone essentially sitting around for five or six years thinking about some crazy assed idea like time slowing down the faster you run, that no one would ever think worth while. Until it changes the world.

Sounds like you should hire a project manager! ;-)
When i was single, I was a slacker mostly interested in partying. I would work just enough for rent and pot.
After our first son arrived 5 years ago (unplanned), I realized I had to make up for lost time, and have been extremely productive ever since, finishing my engineering degree, finally getting a "real" job in the industry, and then leaving that for my startup.
However, my wife constantly says I dont give enough time to the family. If I gave as much time as she wished, I doubt I would be successful.
