I am not a psychologist or life coach, but I will say this: Think about what is important to you, and keep it simple - family time, sleep, exercise, career, etc. Then make quality time in your day for those things. I say quality, not necessarily quantity, because we are busy people, but when you've got some time, do the things you enjoy and the things that are important to you. When you know you've spent time doing those things, you can feel better that your life is balanced. And then you can stop chasing it!
I wrote this post about things that I like to do and how I fit them into my day.
