I love the message of this clip. Too often we focus on what is not working right when we go about implementing change. Change is frequently hard enough, so when we primarily focus on our weak spots, it can lead to inaction and anxiety. Keep building on your strengths so that your weaknesses become irrelevant. Make sure you take time to analyze your successful practices and people so that you can replicate those actions in other areas of yourself or your organization. (Todd Whitaker shares the same sentiment about focusing on your good people in his book Shifting the Monkey.)
Dan Heath and his brother Chip Heath wrote the book Switch: How to Change When Change is Hard.
