Even in popular culture it is highlighted that the beginning of wisdom starts with the simple phrase, "I do not know".Why is it so difficult to say, i dont know when you are in the middle of a discussion?
Does it matter that you can not answer a question? Does it mean when you say, i do not know, that you are less worth then others?
Or is it as simple answer to this that it means you just have more to learn?
Dont be afraid of not knowing
