What's the write way to balance things?

My life is pretty...busy...right now (that's an understatement). I'm thirty years old, I have a wife and two kids, I go to college full time, I'm a stay-at-home Dad, and I have a part-time job (which I absolutely hate). I'm also a writer, a reader, and a gamer, obviously. But those last three are extremely hard to fit into my schedule and keep everything balanced. I know I should focus mostly on writing, as that is the one that has the highest chance of paying off in the end. But reading and gaming are important, too. They provide inspiration and relaxation, and allow me to "get away" from my otherwise hectic and busy life. We all need some time to ourselves, right?

So the problem I face is how to balance it all out. This summer I spent way too much time gaming, and not enough time writing. I had even planned on doing more reading, as well, but I'm not overly concerned about that. But now school is about to begin again, and I will have even less time for writing. I would really like to get a job as a writer (until I become a full-fledged author), but I need more work to show off, and gaming isn't helping.
