What does it mean by the quote, there is more to a person than meets the eye?

This quote means ...

Sort of like ...

Let's say I look at a person. He has a broken leg, an eye patch and is deaf. You don't expect much of him right? But then he does something awesome and you're like 'a person with so much disabilities couldn't have done that'.

So this quote is basically saying ' Don't expect too little of a person from the first look'.

The quote: "There is more to a person than meets the eye" means that you should never judge someone just by their appearance.
