Your body is not who you are. The mind and spirit transcend the body.

My father is an intellectual and physical man, which is a rather unusual combination. He's great. As he brought up me and my brothers and sisters, he ingrained in us that your appearance is not your responsibility, other than that you should not be a slob.

On the wall of his rehabilitation room was a picture of the space shuttle blasting off, autographed by every astronaut now at NASA. On top of the picture it says, "We found nothing is impossible." That should be our motto.

Success is finding satisfaction in giving a little more than you take.

I'm not living the life I thought I would lead, but it does have meaning, purpose. There is love... there is joy... there is laughter.

What I do is based on powers we all have inside us; the ability to endure; the ability to love, to carry on, to make the best of what we have - and you don't have to be a 'Superman' to do it.
