What's the purpose of that?

Good question.  One that has been bothering me for a few weeks now.  It all started with Oprah.  Or, rather the end of Oprah.  During the big week (at least) long Bruhaha surrounding The Last Oprah Show, I happened to see Dr. Phil one night on World News at 6:30.  He was discussing how he was going to make it his life's work to be sure that everyone found that one thing in life that they really get excited about, their "Life's Purpose." The "One Thing" that makes them excited to get up in the morning and is "The Spark" that makes life exciting.  Dr. Phil's advice was to find that one thing that you really want to do, and start taking steps to make it a reality. I paused during my dinner preparations to ponder this for a minute and was hit with the sudden realization that I do not have this "One Thing."  Oh sure, I have lots of hobbies I enjoy, lots of things I like to do, but that "One Thing" that makes me get up in the morning excited about life?  What IS that?  I don't know.  And worse than that, now I realize that I don't know!  Ok, so now I am aware of a previously unknown "void" in my life, how do I go about finding "That Which Will Fill The Void?"  Thanks a lot Dr. Phil!  I didn't even realize I was "incomplete" until you told me I was!
