it’s important to be polite whenever possible. help when and where you can; people will remember. don’t waste, you have more than enough. the first rule of health is cleanliness, and the second is organization. control is unnecessary if management is attainable. don’t keep pins in your pockets. appearing confident is more important—and safer—than being confident. direct instructions have clear results. no one is always right or always wrong. it’s easy to be friendly, but hard to make friends. sleep is important, but not so much as not losing inspiration. nothing ambiguous happens after 10pm; it is either very good or very bad. always carry a pen.
