"A hero is an ordinary individual who finds the strength to persevere and endure in spite of overwhelming obstacles"
-Christopher Reeve ("Superman")

This quote means that a hero is not somebody who has super powers and uses them, like superman, but is an ordinary individual who overcomes obstacles to do something extraordinary. Superman is expected to do stuff "heroes" do, but the real heroes are the ones who don't have super strength or invincibility but still do amazing things. I agree with this quote because if you have super powers or something you are expected to do stuff like Superman, because its normal to you. Not saying that Superman never had to overcome obstacles or anything.
