Internal Beauty and External Appearance

There are lots of people in the world who act really big on the outside but when it comes down to it they are a different person on the inside. However then there are some other people who act really little on the outside but are big on the inside and haven't shown their real potential of what they can do. In some situations I think physical appearances can sometimes relate to personality but then you can be wrong about them, you never judge a book by it's cover. If my internal beauty was directly related to my external appearance then i think sometimes i can be big on the outside and little on the inside. But then other times i think i can be little on the outside but then big on the inside.
