To find out anyone's true love, and what drives them, look at their calendar and their checkbook. I try to do that in my own life to make sure my priorities are not straying. In fact, I have my Outlook calendar color coded by different areas of my life- church, family, work, non-profit, health, entertainment, etc. This helps me see where I'm spending my time.
This is a very good idea, I know I am falling short on this aspect.
