Achieving a balanced lifestyle

How can I adjust my schedule so as to bring about a healthier equalization between the time I spend at work and the time I devote to the rest of life's activities and demands? I've really tried to do this, but it seems that something suffers no matter what I do. Besides, I don't think I've ever met anyone who has been able to put it all together. What does a "balanced" life look like in your opinion? How can I have that kind of life?
