There is a book I like to recommend with regard to these sorts of concerns. It is: Let Your Life Speak: Listening for the Voice of Vocation by Parker J. Palmer, Jossey-Bass, 2000. Palmer writes: "Before you tell your life what you intend to do with it, listen for what it intends to do with you. Before you tell your life what truths and values you have decided to live up to, let your life tell you what truths you embody, what values you represent." (Pg. 3) It is an inspirational & thoroughly wonderful little book. I could not recommend it more highly...

P.S. Reading Let Your Life Speak is what made me a "wise old troll"...
