You will give yourself peace of mind if you perform every act of your life as if it were you last.
Marcus Aurelius 121
We shrink from change; yet is there anything that can come into being without it? What does Nature hold dearer, or more proper to herself? Could you have a hot bath unless the firewood underwent some change.. is it possible for any useful thing to be achieved without change? Do you not see, then, that change in yourself is of the same order, and no less necessary to Nature?
Marcus Aurelius 121
