For nowhere either with more quiet or more freedom from trouble does a man retire than into his own soul, particularly when he has within him such thoughts that by looking into them he is immediately in perfect tranquility; and I affirm that tranquility is nothing else than the good ordering of the mind.

Loss is nothing else but change, and change is Nature's delight.

Do not think that what is hard for you to master is humanly impossible; but if a thing is humanly possible, consider it to be within your reach.

To live each day as though one's last, never flustered, never apathetic, never attitudinizing - here is the perfection of character.

You are making an inopportune rejection of what Nature has given you today, if all your mind is set on what men will say of you tomorrow.

Purge your mind of all aimless and idle thoughts, especially those that pry into the affairs of others or wish them ill.

The perfection of moral character consists in this, in passing every day as the last, and in being neither violently excited nor torpid nor playing the hypocrite.
