A Christian colleague of mine recently recommended this article to me:

I trust we all can learn from this article. I particularly like its view of “work-life integration” as opposed to “work-life balance”. Work is part of our life, so perhaps it is better to think about how to incorporate work in our life (secular as well as spiritual).
