"In the traditions of Covey and Fitz, Quinn puts timeless wisdom into a timely container of loving letters to his college freshman son. As I read it, I found myself often agreeing, sometimes pondering, occasionally quarreling, but always knowing that this is good stuff.

Put away the chicken soup: Letters to Garrett is a hearty stew."
-- Philip H. Mirvis, author and board cochair, Foundation for Community Encouragement
