Application and capacity
Eminence requires both. When both are present, eminence outdoes itself. The mediocre people who apply themselves go further than the superior people who don’t. Work makes worth. You purchase reputation with it. Some people are unable to apply themselves to even the simplest tasks. Application depends almost always on temperament. It is all right to be mediocre at an unimportant job : you can excuse yourself by saying you were cut out for nobler things. But to be mediocre at the lowest of jobs, rather than excellent at the highest, has no excuse at all. Both art and nature are needed, and application makes them complete.
