Thanks for writing this. I am in the same position, working full-time in a semi-demanding job, with a wife, son, big lawn to mow, etc. I've been working nights and weekends for over a year and am 2 months away from launching.
My schedule looks almost exactly like yours. On Saturdays, I watch my son while my wife is at work, and I have the same mixed feelings about spending time with my son vs. working on my startup. Then I feel guilty for having mixed feelings...you know how it goes.
Good luck with your startup. Keep fighting the good fight!
Of course--but at least for me, I don't have enough spare cash flow to outsource all the handyman stuff. And if I did, I've found that the time cost of finding someone and managing them can be at times almost as much as doing it myself. So I end up paying more for a very small savings in time.
Actually, our current strategy is to stop watering the lawn and have a big patch of dirt in the front (our area has a drought). :) Disadvantages: dirt tracked in the house, neighbors hate us.
