Sometimes, if you want to learn something new, you have to admit that you don't know something -- and that can be hard on your self-esteem. But you have to keep your mind on the greater goal of furthering your education today -- if you encounter a concept or term that you're unfamiliar with, let it be known. Even if you have to raise your hand in a meeting full of important folks, do it. Chances are, you aren't the only person who needs an explanation.
