Nothing else so inspires and heartens people as words of appreciation. You and I may soon forger the words of encouragement and appreciation that we utter now, but the person to whom we have spoken them may treasure them and repeat them to themselves over a lifetime
Dale CarnegieSo if you aspire to be a good conversationali st, 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
Dale CarnegieTell a child, a husband or an employee that he is stupid or dumb at a certain thing, that he has no gift for it, and that he is doing it all wrong and you have destroyed almost every incentive to try to improve. But use the opposite technique, be liberal with encouragement; make the thing seem easy to do, let the other person know that you have faith in his ability to do it, that he has an undeveloped flair for it - and he will practice until the dawn comes in at the window in order to excel.
