Ambition means tying your well-being to what other people say or do. Self-indulgence means tying it to the things that happen to you. Sanity means tying it to your own actions.
Marcus AureliusRemember that man lives only in the present, in this fleeting instant; all the rest of his life is either past and gone, or not yet revealed.
Marcus AureliusPrize that which is best in the universe; and this is that which useth everything and ordereth everything.
