A lot of people do not realize that many organizations consider resilience a core competency of leadership. You cannot demonstrate resilience without experiencing failure. The courage to fail grows out of your willingness to be vulnerable.
The more exposure people have to different aspects of your personality, the more they will understand you. In the absence of information, people will create their own stories. It is hard as hell to deconstruct an inaccurate perception. Manage perceptions by freely sharing who you are... with boundaries.
