At first it started out as being a part of the job. Then it became a part of me. After my inquiring of a decision made, or a thought had, even feelings....I would ask then hear myself ask the person, "Why?" I felt a need to know more information and to gain additional insight into the responder.
This has become my thing! Even catch myself wondering the why to my own thoughts, feelings, and decisions. Because hey you never know when someone will ask me why!
There is even a book that I would like to reas entitled, "Start with Why". Check it out, too! You never know what you may learn! :-)
