In talking with people, don't begin by discussing the things on which you differ. Begin by emphasizing - and keep on emphasizing - the things on which you agree. Keep emphasizing, if possible, that you are both striving for the same end and that your only difference is one of method and not of purpose.

Dale CarnegieWhen we have a brilliant idea, instead of making others think it is ours, why not let them cook and stir the idea themselves.
Dale CarnegieIf you can't sleep, then get up and do something instead of lying there worrying. It's the worry that gets you, not the lack of sleep.
