People who have attained things worth having in this world have worked while others have idled, have perservered while others gave up in despair, and have practiced early in life the valuable habits of self-denial, industry, and singleness of purpose.
Discreetly keep most of your radical opinions to yourself. When with people be a listener a large part of the time. Be considerate in every word and act, and resist the tendency to say clever things. The best evidence of your culture is the tone and temper of your conversation.
People around you are quick to read your attitude of thought toward them. Inner thoughts and feelings are communicated in ways other than by the spoken word.
