Here is the rule to remember in the future, When anything tempts you to be bitter: not, 'This is a misfortune' but 'To bear this worthily is good fortune.'

When you have trouble getting out of bed in the morning, remember that your defining characteristic-what defines a human being-is to work with others.

Nothing befalls any man which he is not fitted to endure.

The universe is a single life comprising one substance and one soul.

Confine yourself to the present.

Our life is what our thoughts make it. Do every act of your life as if it were your last. In a word, your life is short. You must make the most of the present with the aid of reason and justice. Since it is possible that you may be quitting life this very moment, govern every act and thought accordingly.

Without a purpose, nothing should be done.
