PRINCIPLE 1 The only way to get the best of an argument is to avoid it. PRINCIPLE 2 Show respect for the other person’s opinions. Never say, “You’re … - Dale Carnegie

foundational principles — don’t criticize, condemn, or complain; talk about others’ interests; if you’re wrong, admit it; let others save face. Such principles don’t make you a clever conversationalist or a resourceful raconteur. They remind you to consider others’ needs before you speak. They encourage you to address difficult subjects honestly and graciously. They prod you to become a kinder, humbler manager, spouse, colleague, salesperson, and parent. Ultimately, they challenge you to gain influence in others’ lives not through showmanship or manipulation but through a genuine habit of expressing greater respect, empathy, and grace.

"When we are harassed and reach the limit of our own strength, many of us then turn in desperation to God-"There are no atheists in foxholes." But why wait till we are desperate? Why not renew our strength every day? Why wait even until Sunday? For years I have had the habit of dropping into empty churches on weekday afternoons.
When I feel that I am too rushed and hurried to spare a few minutes to think about spiritual things, I say to myself: "Wait a minute, Dale Carnegie, wait a minute. Why all the feverish hurry and rush, little man? You need to pause and acquire a little perspective." At such times, I frequently drop into the first church that I find open.
Although I am a Protestant, I frequently, on weekday afternoons, drop into St. Patrick's Cathedral on Fifth Avenue, and remind myself that I'll be dead in another thirty years, but that the great spiritual truths that all churches teach are eternal. I close my eyes and pray. I find that doing this calms my nerves, rests my body, clarifies my perspective, and helps me revalue my values. May I recommend this practice to you?"

Honest appreciation got results where criticism and ridicule failed.
