"There is no substitute for Excellence – not even success. Success is tricky, perishable and often outside our control; the pursuit of success makes a poor cornerstone, especially for a whole personality. Excellence is dependable, lasting and largely an issue within our own control; pursuit of excellence, in and for itself, is the best of foundations,” The Heart of the Order, by Thomas Boswell (Doubleday, 1989).
