From Adam Grant’s book “Think Again,” which is all about learning to re-think what you believe in.

We learn more from people who challenge our thought process than those who affirm our conclusions. Strong leaders engage their critics and make themselves stronger. Weak leaders silence their critics and make themselves weaker. This reaction isn’t limited to people in power. Although we might be on board with the principle, in practice we often miss out on the value of a challenge network.

Do you have a “Challenge Network” as a leader? Do you actively seek out people who are going to challenge what you do, or are you surrounded by people who agree with you. Progressive leaders seek out a challenge network and want people to question why they do what they do. It makes them stronger leaders. Unfortunately, once we get into a leadership position, we often don’t want people around us who disagree with us, and we stop getting better.
