“Such are the vicissitudes of the world, through all its parts, that day and night, labor and rest, hurry and retirement, endear each other; such are the changes that keep the mind in action: we desire, we pursue, we obtain, we are satiated; we desire something else and begin a new pursuit.” —Samuel Johnson
