Not much time, eh? ;-)

Well, I see one obvious thing to cut without sacrificing your work or children, and that is the commute. Get yourself a gig that you can walk/bike in a short amount of time. Choose it well and you'll get exercise too.

Now, I know what you're thinking right now, I can't! Because of X, Y, and Z. Sure, understood in the short term. But, ask yourself where you want to be in a year or two?

If you start looking now, you can find a closer or remote job, or move home to be near a great job---over the medium term. Want to know how I know? Because, I've been doing it for twenty years. So when people say, "oh, I couldn't possibly" BS is called quickly. Good luck.
