“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.”

“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.”

“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.”

“You have power over your mind - not outside events. Realize this, and you will find strength.”

“Anything in any way beautiful derives its beauty from itself and asks nothing beyond itself. Praise is no part of it, for nothing is made worse or better by praise.”

“Because your own strength is unequal to the task, do not assume that it is beyond the powers of man; but if anything is within the powers and province of man, believe that it is within your own compass also. Marcus Aurelius”

“For it is in your power to retire into yourself whenever you choose.”
