Sometimes, much of the time, the best answer to any question is "I don't know," especially when you don't know. I don't believe we hear those words enough. If we do hear them, we let them leave our heads as fast as they got into our heads. What follows "I don't know" should then be a single thought in our minds: What is the answer to that question and then delve into some research. Oh sure we may know a few things about a thing or two, but we are all guilty of claiming to know something we know nothing about.
