If you don't believe in you.. who will?

I've spent the last hour listening to Shadow by Colbie Caillat, and just looking out and watching the airplanes fly by. When I'm alone I dream a little too much. I really want to leave this place. It's been my dream as long as I can remember. I believe in dreams. It might be pathetic and stupid but I really do... I believe in my dreams, and I believe they will be my reality some day. I feel like you have to believe in you, because if you don't believe in you.. who will?
