A favorite quote of mine.
"Never judge ... a book by the way it's covered; for inside those tattered pages, there's a lot to be discovered."
Too many times, superficial aspects of a person tend to be the judge of the person's worth. Look no further than the media and some groups. Why should it matter what the cover of a book looks like? This lead to Reverend Doctor Martin Luther King Jr's "I Have A Dream" speech.
