In his commencement address to Simmons College, David Weinberger addressed the feeling that some of us have after achieving an advanced degree in our field and not the sense of mastery we expected. The feeling that we may not know as much as some of our peers or professors. He suggests this lack of confidence may be a good thing.
But here’s why it’s good to get comfortable with always having a little lack of confidence. First, if you admit no self-doubt, you lose your impulse to learn. Second, you become a smug, know-it-all and no one likes you. Third, what’s even worse, is that you become a soldier in the army of ignorance. Your body language tells everyone else that their questions are a sign of weakness, which shuts down what should have been a space for learning.
