What are Mr. Browne's precepts?

In RJ Palacio's 2012 novel, Wonder, the character of August "Auggie" Pullman has been homeschooled until fifth grade because of insecurities owing to his birth defect. When he enters public school, he and his parents fear that he will be bullied because of his appearance. While this fear holds true to some extent, the effects are mitigated by the positive influence of his teacher, Mr. Browne. Mr. Browne tells his class that he used to work on Wall Street, but he left to become a teacher. Each month, Mr. Browne gives his class a group of precepts to motivate and guide them. The precepts are as follows:
