How Do You Do It All?

I understand that my gaming habits require prep time. Prepping for my D&D campaign, doing the art and making the tokens and minis, assembling miniatures for my army, painting them when I get around to it. And gaming days/nights require 3-8 hour blocks of time tied to an average of 6-9 times that I game a month.
So as the title says, how do you do it all? My gaming involves D&D and Warmachine/Hordes with Malifaux and Mouse Guard on the horizon. I don't have children to watch or a second job but am finding it hard to balance time and scheduling with some of my other interests and responsibilities. Thank God I don't play video games.
