Some are born with knowledge, some derive it from study, and some acquire it only after a painful realization of their ignorance. But the knowledge being possessed, it comes to the same thing. Some study with a natural ease, some from a desire for advantages, and some by strenuous effort. But the achievement being made, it comes to the same thing.
ConfuciusThe superior person is calm and composed; the lesser person is continuously worried and distressed.
ConfuciusThe gentleman has nine cares. In seeing he is careful to see clearly; in hearing he is careful to hear distinctly; in his looks he is careful to be kind, in his manner to be respectful, in his words to be sincere, in his work to be diligent. When in doubt he is careful to ask for information; when angry he has a care for the consequences; and when he sees a chance for gain, he thinks carefully whether the pursuits of it would be right.
Confucius
