I've always thought that if you work really hard at something, you can get it.
When I get home from a heavy work day, I make sure I get outside with the kids. I don't think there's any better cure than being active as a family outside.
There's always going to be a ball up in the air, and what I try to do is make sure that ball is never the kids. If that means sacrificing a social event or having fewer work commitments, it's worth it.
I prioritize the things that need to get done at work, and I ask myself where I'm spending the majority of my time. The answer to that question always needs to be 'with my family.'
