Remember why you are there! Get outside yourself, It's not about you, it's about presenting an award to someone deserving.
Now... If I sound harsh.... I am not telling you anything different than I tell myself, and I have had to do that... quite a few times early on!! By taking the focus off myself as much as I possibly can, getting outside myself... If I have a job to do, I make myself think only of that.
I do that at parties at our house... God knows I was the first to go wild and the last to stop... Now I give myself an assignment... food, entertainment, whatever... something to make the guests feel special... Me? I am not that important.
It takes practice, and it's not always easy, and I'm not perfect...
NOW... get out there, give that award with a smile and a handshake and make that person's day!! Then, if you have to, leave.
