Opening half of a famous saying of Confucius in
《论语·卫灵公》 (Analects, Wei Ling Gong):
工欲善其事,
必先利其器 - 'An artisan who wants to do his work well must first sharpen his tools.' Zigong had asked about practicing virtue; Confucius answered with this metaphor: to live well among men, first seek out the good and the wise.
