From Alexander the Platonic, not frequently nor without necessity to say to any one, or to write in a letter, that I have no leisure; nor continually to excuse the neglect of duties required by our relation to those with whom we live, by alleging urgent occupations.
Marcus AureliusSuch as are thy habitual thoughts, such also will be the character of thy mind; for the soul is dyed by the thoughts.
Marcus Aurelius
