You might look at my CV and see I've had 12 jobs, but I've been to over 450 auditions so I've heard 'no' a lot more than I've heard 'yes'. So if I go in looking only to meet my own standards, then that will make taking that rejection a little bit easier. And when I do get that job it will seem like icing on the cake.
I shall take all the troubles of the past, all the disappointments, all the headaches, and I shall pack them in a bag and throw them in the East River.
