I want so badly to embed it for you, but I can't find an embeddable copy of the video since it's from television. Do yourself (and your soul) a favor: go watch Susan Boyle sing.
Update: I found an embeddable version!
Susan Boyle on Britain's Got Talent

If you've ever felt disappointed by your life; if you've ever loved; if you've ever been hurt; if you've ever lived, you will be touched by this song.
More importantly, I think you'll be inspired. Just because you haven't got the looks of a model doesn't mean you're invisible. It doesn't mean you don't have anything to offer the world. Take a cue from Susan Boyle - put on your fancies, get cheeky, and go after your dream!
