First and foremost, be faithful to your superiors, keep all promises, refuse the friendship of all who are not like you; and if you have made a mistake, do not be afraid of admitting the fact and amending your ways.
ConfuciusIf I give a student one-fourth of what he should know, I expect him to get the other three-fourths himself, otherwise I do not want him as a student.
Confucius
