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 AureliusIf unwilling to rise in the morning, say to thyself, 'I awake to do the work of a man.'
Marcus AureliusAlways 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.
