You have to decide what your highest priorities are and have the courage — pleasantly, smilingly, nonapologetically — to say “no” to other things. And the way to do that is by having a bigger “yes” burning inside. The enemy of the “best” is often the “good.” – Stephen Covey
A cardinal principle of Total Quality escapes too many managers: you cannot continuously improve interdependent systems and processes until you progressively perfect interdependent, interpersonal relationships. – Stephen Covey
