Wonder

    Never outgrow your sense of wonder.  Wonder will inspire you to explore all the rich things that life can give you, keeping you modest in the process.  As you get older, you will want to think you know things, and because you already know things it will dampen your interest in unfamiliar ideas and subjects.  Instead, try to retain the innocence that claimed you when you were born, so you can remember the old things and still be open to learning new things.  Never laugh at those who keep their toys, or who become easily amused, no matter how old they are.  You will find that the young and the elderly have the same needs, and dream of the same stuff.  We all devolve to the state of youth after life has come full circle.  That lifelong quest for knowledge will have meant nothing unless you find a way to apply it well.
