Little courtesies that oil the cogs of the grind of everyday life

Little phrases such as ‘I’m sorry to trouble you,’ ‘Would you be so kind as to—?’ ‘Won’t you please?’ ‘Would you mind?’ ‘Thank you’—little courtesies like these oil the cogs of the monotonous grind of everyday life—and, incidentally, they are the hallmark of good breeding.

To be a good conversationalist

…if you aspire to be a good conversationalist, be an attentive listener. To be interesting, be interested. Ask questions that other persons will enjoy answering. Encourage them to talk about themselves and their accomplishments.

Remember that name…

…the average person is more interested in his or her own name than in all the other names on earth put together. Remember that name and call it easily, and you have paid a subtle and very effective compliment.

Arouse in the other person an eager want

Action springs out of what we fundamentally desire… and the best piece of advice which can be given to would-be persuaders, whether in business, in the home, in the school, in politics, is: First, arouse in the other person an eager want. He who can do this has the whole world with him. He who cannot walks a lonely way.
