If you don’t understand something clearly that you are being taught…speak up. If you feel something is confusing, or you are unsure of exactly what to do…ask about it. If you need clarification or something repeated to make sure you got it…request it. If you feel lost, forgot something, or feel like you are falling behind…bring it up. Nodding your head, saying “yeah, yeah” and pretending to know things you don’t is right up there with one of the worst things you can do when you hire someone to help you and your career.
