<p>EVERYONE (except for a handful of blowhards) will have the feeling that he/she was the “mistake” and soon a member of the adcom will be knocking at your door and asking you to leave. Soon you will discover that there are areas in which you are not only really competent but excel. It will happen. You are meant to be there. Your admission was not a fluke, not a mistake. Just remember that there are thousands of other who got the “thin envelopes” and would give anything to be where you will be. Don’t waste your opportunities, if only for them.</p>
