Knowledge is like underwear. It is useful to have it, but not necessary to show it off.
Even if you are the smartest person in the room, you don't have to spend all of your energy proving it. Spend more time being interested, not interesting. Jesus was obviously smarter than everyone, but His humility and service to others is a model of true leadership. Focus on being more "Humble and Kind" today and you will get all the attention you need.
But he gives more grace. Therefore it says, "God opposes the proud, but gives grace to the humble."
