Quality is not just the absence of defects; it is the presence of value.
质量不仅仅是缺陷的缺失；它是价值的存在。
The best teacher is the one who suggests rather than dogmatizes, and inspires his listener with the wish to teach himself.
译文：每天都要纠正自己的过错。如果哪天没有发现过失，那就会自以为是；如果每天都觉得无过错，那就会寸步难进。天下聪明俊秀的人才不少，他们之所以不去努力地培养德行，扩大事业，是因为受了得过且过的思想影响，耽误终生。
