Discreetly keep most of your radical opinions to yourself. When with other people be a listener a large part of the time. Be considerate in every word and act. Never look down on others, cultivate tolerance towards them.
Patiently listen to opinions which oppose yours. It is a wise thing never to boast, never to speak of yourself unless it is imperative, never to speak ill of another.
Be slow to pass judgment. Examine and judge the contents of your own mind rather than that of others. Give preference to pleasant subjects.
Rule your moods. Resist the tendency to say clever things. The best evidence of your culture is the tone and temper of your conversation. Charitable judgment will help you to progress most rapidly in love, gentleness, and sympathy.
