As I get older especially I find myself with less and less time to learn things that aren't somehow useful to my life, like game programming. It's sad.
Take a stab at it with love. If you already code professionally you can have a simple platformer or asteriods type game up in running in an hour or two
Do you have kids? If so, learn to write a game with your code by your side! That's what I'm doing, and I generally feel the same as you (NO GODAMN TIME!) :)
