Dale Carnegie said this quote
“ Could my opponents be right? Partly right? Is there truthor merit in their position or argument? Is my reaction onethat will relieve the problem, or will it just relieve any frustration? Will my reaction drive my opponents further awayor draw them closer to me? Will my reaction elevate the estimation good people have of me? Will I win or lose?What price will I have to pay if I win? If I am quiet about it,will the disagreement blow over? Is this difficult situationan opportunity for me? ”
