His individual quality does not depend merely on the display of superior enterprise and energy, although, of course, he may and should be as enterprising and as energetic as he can.

It depends upon the actual excellence of the work in every respect,--an excellence which can best be achieved by the absorbing and exclusive pursuit of that alone.

A man's individuality is projected into his work.

He does not stop when he has earned enough money, and he does not cease his improvements when they cease to bring in an immediate return.

He is identified with his job, and by means of that identification his individuality becomes constructive.
