I admire Harville Hendrix.  he is founder of Imago therapy which is a widely accepted modality for couples therapy.  I am a believer in his theory, but that's not the sole reason for my admiration.

Harville Hendrix was a professor teaching couples therapy to psychology students when he was divorced.  In fact, her went from the courthouse to teach a class. Here he was, an expert in the field of partner counseling, in a failed marriage.  As it turns out his students knew where he was and greeted him with compassion.  A discussion about relationships ensued where each student shared personal details about past and present relationships.

At the end of class a student asked him what keeps couples together.  He answered: I have absolutely no idea.

That is why I hold him in such high esteem.  When a person regarded as an expert can say those words in the context of their expertise great powers are unleashed.  Having the humility to question ones self and to say so out loud is a great strength. Removing ego and opening the door to new ideas is where true innovation is born.

Over the next year he developed Imago Therapy and subsequently changed the lives of thousands of people.
