“Confine yourself to the present.”

“As far as you can, get into the habit of asking yourself in relation to any action taken by another: "What is his point of reference here?" But begin with yourself: examine yourself first.”

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

“Never let the future disturb you. You will meet it, if you have to, with the same weapons of reason which today arm you against the present.”

“Dwell on the beauty of life. Watch the stars, and see yourself running with them.”

“Very little is needed to make a happy life; it is all within yourself in your way of thinking.”

“In everything that you do, pause and ask yourself if death is a dreadful thing because it deprives you of this”
