Overview
Yes, you might be missing one piece of information, but you should be able to go on without it. Use your intuition and your logic. After all, even if you're missing one piece of a jigsaw puzzle, you still get a pretty good idea of what the picture is when you're done. So don't delay yourself just because someone hasn't gotten back to you with a confirmation or a minor detail. You know enough to keep going, so don't lose momentum!
