According to Bob Sutton, the essence of wisdom is “strong opinions, weakly held.” I feel a bit gratified by that because I was just explaining to a coworker the other day that I will fight hard for the things I believe, but if you can convince me that I’m wrong, I’m perfectly willing to fight hard for the things you believe. I didn’t know that made me wise, but I’m glad to hear that it does. I think that if anyone really looks hard at the number of times that they’ve been wrong about something they really strongly believed, they would not have high confidence in the things they believe at the moment. Everybody seems to be wrong at least half the time.
