If you remember nothing...

then don't worry about anything. But if you can remember one thing, remember this: they don't know how scared you are. They don't know how you feel about yourself and how much you know. Whatever it is you do; write, direct sales (like At Home America), dog watching, or even stamping envelopes... whomever you talk to, they don't know.  Use it and become even better than you already are.
