I will admit to struggling with this. I am a lawyer. My career consists of giving clients the right answer within my area of expertise. I try very hard not to be a "know-it-all" by doing two things. 1. Realize that my area of expertise is very limited and just because I have a great deal of knowledge in one area does not generally make me right in other areas. 2. Quickly admit when I am wrong. The lesson is one in humility. Even the most intelligent have important areas in which they have almost no knowledge or experience. For example, I am highly educated, but I feel lost in the crypto currency discussions that happen on Steemit and when my car breaks down I just open the hood and stare helplessly at the smoke slowly rising from a part that I cannot name. If we all knew all of the right answers already, Steemit would be almost useless to us. Thanks for reading.
