Why should any of these things that happen externally distract thee? Give thyself leisure to learn some good thing: cease roving to and fro.
Marcus AureliusCultivate these, then, for they are wholly within your power: sincerity and dignity; industriousness; and sobriety. Avoid grumbling, be frugal, considerate, and frank; be temperate in manner and speech; carry yourself with authority.
Marcus AureliusLook within, for within is the wellspring of virtue, which will not cease flowing, if you cease not from digging.
Marcus AureliusObserve and contemplate on the hidden things of life: how a man's seed is but the beginning, it takes others to bring it to fruition. Think how food undergoes such changes to produce health and strength. See the power of these hidden things which, like the wind cannot been seen, but its effects can be.
Marcus Aurelius
