When the first Superman movie came out, I gave dozens of interviews to promote it. The most frequent question was: What is a hero? My answer was that a hero is someone who commits a courageous action without considering the consequences. Now my definition is completely different. I think a hero is an ordinary individual who finds the strength to persevere and endure in spite of overwhelming obstacles.

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

So many of our dreams at first seem impossible, then they seem improbable, and then, when we summon the will, they soon become inevitable.

We can either watch life from the sidelines, or actively participate... Either we let self-doubt and feelings of inadequacy prevent us from realising our potential, or embrace the fact that when we turn our attention away from ourselves, our potential is limitless.

I have more awareness of other people and, I hope, more sensitivity to their needs. I also find that I'm more direct and outspoken.

Living a life with meaning means spreading the word. Even if you can't move, you can have a powerful effect with what you say.

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.
