Value.

"If you feel your value lies in being merely decorative I fear that some day you might find yourself believing that is all you really are. Time erodes all such beauty, but what it cannot diminish is the wonderful workings of your mind, your humor, your kindness and your moral courage; these are the things I cherish so in you."
