A good deed, "said the prophet Mohammed, "is one that brings a smile of joy to the face of another." Why will doing a good deed every day produce such astounding efforts on the doer? Because trying to please others will cause us to stop thinking of ourselves: the very thing that produces worry and fear and melancholia.

Dale CarnegieFlaming enthusiasm, backed up by horse sense and persistence, is the quality that most frequently makes for success.
