Next to knowing when to seize an opportunity, the most important thing in life is to know when to forego an advantage.
Benjamin DisraeliTaste, when once obtained, may be said to be no acquiring faculty, and must remain stationary; but knowledge is of perpetual growth and has infinite demands. Taste, like an artificial canal, winds through a beautiful country, but its borders are confined and its term is limited. Knowledge navigates the ocean, and is perpetually on voyages of discovery.
