This past Spring my daughter completed two years teaching high-school math in the Dallas-Fort Worth area with Teach For America https://www.teachforamerica.org. She is staying on another year so she can see the first class she taught graduate. Now in her third year, she is participating in a semester-long professional-development program sponsored by Teaching Trust http://www.teachingtrust.org/.
She showed me the resource they are working with: The Speed of Trust, by Stephen M. R. Covey, whose father, Stephen R. Covey, wrote The Seven Habits of Highly Effective People.
So many family enterprise stories come to mind with trust as a factor–the good, bad and in-between. Family businesses built on strong trust among family members are going to win out over any other kind of business, time and again.
