People who have accomplished work worthwhile have had a very high sense of the way to do things. They have not been content with mediocrity. They have not confined themselves to the beaten tracks; they have never been satisfied to do things just as others so them, but always a little better. They always pushed things that came to their hands a little higher up, this little farther on, that counts in the quality of life's work. It is constant effort to be first-class in everything one attempts that conquers the heights of excellence.
