Do not confuse "duty" with what other people expect of you; they are utterly different. Duty is a debt you owe to yourself to fulfill obligations you have assumed voluntarily... Difficult it may be, but the reward is self-respect. But there is no reward at all for doing what other people expect of you, and to do so is not merely difficult, but impossible...So learn to say No—and to be rude about it when necessary.
Robert Heinlein /Time Enough for Love/
