" What a waste of the essence of a man that he should never give enough of himself to any cause, that he should always hear that passive, cowardly voice uppermost which counts the cost and puts caution first. One would grow old and die with the power of one’s soul untasted. "

― Anne Perry , The William Monk Mysteries: The Face of a Stranger / A Dangerous Mourning / Defend and Betray (William Monk, #1-3)
