Every man should, indeed, carefully compare his force with his undertaking; for though we ought not to live only for our own sakes, and though therefore danger or difficulty should not be avoided merely because we may expose ourselves to misery or disgrace; yet it may be justly required of us, not to throw away our lives upon inadequate and hopeless designs, since we might, by a just estimate of our abilities, become more useful to mankind.
–Samuel Johnson, The Rambler, #129, “The Folly of Cowardice and Inactivity”
