The more you know, the more you will realise that there are many things that you do not know. Regardless of one’s prestigious title, rank or fame, those who are truly knowledgeable are the ones that choose to speak less and listen more. When they do speak, it is one of wisdom and humility. They do not need to suck up all the air in the room. Instead they do their best to allow others to express their views and opinions. They ask great questions with sincere curiosity that generates trust from the other parties and this creates an engaging atmosphere where people can learn something while enjoying themselves.
