“Never esteem anything as of advantage to you that will make you break your word or lose your self-respect.”

“So you know how things stand. Now forget what they think of you. Be satisfied if you can live the rest of your life, however short, as your nature demands. Focus on that, and don't let anything distract you. You've wandered all over and finally realized that you never found what you were after: how to live. Not in syllogisms, not in money, or fame, or self-indulgence. Nowhere.”

“Though you break your heart, men will go on as before.”

“A man should always have these two rules in readiness. First, to do only what the reason of your ruling and legislating faculties suggest for the service of man. Second, to change your opinion whenever anyone at hand sets you right and unsettles you in an opinion, but this change of opinion should come only because you are persuaded that something is just or to the public advantage, not because it appears pleasant or increases your reputation.”

“If you are distressed by anything external, the pain is not due to the thing itself, but to your estimate of it; and this you have the power to revoke at any moment.”

“You always own the option of having no opinion. There is never any need to get worked up or to trouble your soul about things you can't control. These things are not asking to be judged by you. Leave them alone.”

“If you are pained by external things, it is not they that disturb you, but your own judgement of them. And it is in your power to wipe out that judgement now.”
