There is no such thing as can't.

It never occurred to me that I was a leading man until I was 19 years old. I had been acting since I was 10, so that's nine years and 30 or 40 plays, in school and summer stock, professional theater, too.

I think we all have a little voice inside us that will guide us. It may be God, I don't know. But I think that if we shut out all the noise and clutter from our lives and listen to that voice, it will tell us the right thing to do.

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.

I get pretty impatient with people who are able-bodied but are somehow paralyzed for other reasons.

A hero is someone who, in spite of weakness, doubt or not always knowing the answers, goes ahead and overcomes anyway.

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.
