Truth.  Outside of my immediate family, I've never been so challenged to speak the truth in love, keep short accounts, and forgive with extravagance.  Leading multi-faceted people in one unified direction is not for the faint of heart.  Honestly, I was humbled by my consistent need to ask forgiveness for myself.  My knees and my heart were raw in a good tenderized kind of way by the end of my term.
