As a self-acknowledged guinea pig for many of his dad's theories, Sean Covey is a living example of someone who has taken each of the seven habits to heart: be proactive; begin with the end in mind; put first things first; think win-win; seek first to understand, then to be understood; synergize; and sharpen the saw. He includes a comical section titled "The 7 Habits of Highly Defective Teens," which includes some, shall we say, counterproductive practices: put first things last; don't cooperate; seek first to talk, then pretend to listen; wear yourself out... Covey's humorous and up-front style is just light enough to be acceptable to wary teenagers, and down-and-dirty enough to really make a difference. (Ages 13 and older) --Emilie Coulter
