Don't let your imagination be crushed by life as a whole.
Men exist for each other. Then either improve them, or put up with them.
When thou art above measure angry, bethink thee how momentary is man's life.
Remember that the sole life which a man can lose is that which he is living at the moment.
Vex not thy spirit at the course of things, they heed not thy vexations
Confine yourself to the present.
