Leaders need strength to be successful. While this obvious truth is widely recognized, opinions differ on what constitutes “strength.” In the eyes of many, strength means standing firm, winning your position, exuding confidence, and minimizing vulnerability. At PMC, our clients are often surprised to hear that we see vulnerability as a key source of leadership strength. Which is stronger, a leader who advocates a position and stands firm until others bend? Or a leader who advocates a position while remaining open to different views, even inviting challenge from others? Leaders who take the path of openness will naturally feel vulnerable. Paradoxically, this vulnerability is not a sign of weakness, but rather a clear indication of leadership strength.
