Think for a minute of all the voices of authority that exist in your life. Your list most likely includes people you trust and admire, books by authors and experts, perhaps religious figures you know. We tend to put our trust (sometimes exclusively) in external authorities.
I was visiting with a leader I had respected from a distance for some time. As we talked, he kept looking at his watch and glancing around at other people. He would grunt a few responses and then glance down at his watch or look around again, making eye contact with someone walking by or nodding his head in acknowledgement to them. It didn't take me long to realize this person was not engaged at all with me. It felt not just disappointing but deeply off-putting--like I didn't count or wasn't important enough to him to pay targeted attention to.
