Read this wise post by Wally Bock on work/life balance and what's next. An excerpt:
Most of the times in my life when I’ve been the happiest and the most productive, my life hasn’t been very balanced at all. But I was able to make choices based on what I thought was important at the time.
And the unhappy, unproductive times? Those were the ones where I didn’t have a choice. When circumstances or other people or the consequences of earlier choices took away my choice, life was not very good at all.
