Men exist for each other. Then either improve them, or put up with them.

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

Your days are numbered. Use them to throw open the windows of your soul to the sun. If you do not, the sun will soon set, and you with it.

Think of the country mouse and of the town mouse, and of the alarm and trepidation of the town mouse.

Be not careless in deeds, nor confused in words, nor rambling in thought.

If you separate from . . . everything you have done in the past, everything that disturbs you about the future . . . and apply yourself to living the life that you are living-that is to say, the present-you can live all the time that remains to you until your death in calm, benevolence, and serenity.

Every man's life lies within the present; for the past is spent and done with, and the future is uncertain.
