Let every action aim solely at the common good.

You have to assemble your life yourself - action by action.

A man's worth is no greater than his ambitions.

Always run to the short way; and the short way is the natural: accordingly say and do everything in conformity with the soundest reason. For such a purpose frees a man from trouble, and warfare, and all artifice and ostentatious display.

Think on this doctrine, - that reasoning beings were created for one another's sake; that to be patient is a branch of justice, and that men sin without intending it.

The whole universe is change and life itself is but what you deem it - either gratefully better than or bitterly worse than something else that you alone choose.
