Reason and judgment are the qualities of a leader.

Like dogs in a wheel, birds in a cage, or squirrels in a chain, ambitious men still climb and climb, with great labor, and incessant anxiety, but never reach the top.

If the career you have chosen has some unexpected inconvenience, console yourself by reflecting that no career is without them.

So little done, so much to do.
