Teach, Wake, Follow, Avoid...

    Author Unknown

    He who knows not and knows that he knows not
    is simple, TEACH HIM!
    He who knows and knows not that he knows
    is asleep, WAKE HIM!
    He who knows and knows that he knows
    is a wise man, FOLLOW HIM!
    He who knows not and knows not that he knows not
    is a fool, AVOID HIM!
