He that has never known adversity is but half acquainted with others, or with himself. Constant success shows us but one side of the world. For, as it surrounds us with friends, who will tell us only our merits, so it silences those enemies from whom alone we can learn our defects.

Charles Caleb "C. C." Colton (1780-1832) English cleric, writer, aphorist

Lacon: Or, Many Things in Few Words, Vol. 1, § 513 (1820)
