The Medulla Obligation is the siren of the mating dance. "The character of the Medulla Obligation is much more complicated that that of gravity, yet no less powerful and no less consistent." You cannot escape her designs on your life, but you can flow with her and learn to recognize both advantages and pitfalls inherent and inevitable in human interaction.

You can learn when to interact and when to quietly disengage, when your gifts are yours or are to be taken from you. You can learn how to make the best of your "turns at bat" in life to make a difference for you and those important to you, and how to keep yourself viable beyond established expectations.
