Even in such technical lines as engineering, about 15% of one's financial success is due one's technical knowledge and about 85% is due to skill in human engineering, to personality and the ability to lead people.
Dale CarnegieMillions of people have wrecked their lives in angry turmoil, because they refused to accept the worst; refused to try to improve upon it; refused to salvage what they could from the wreck.

Dale CarnegieIn 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 CarnegieBy all means take thought for the tomorrow, yes, careful thought and planning and preparation. But have no anxiety.
