I believe that a life of integrity I the most fundamental source of personal worth. I do not agree with the popular success literature that says that self-esteem is primarily a matter of mind set, of attitude—that you can psych yourself into peace of mind. Peace of mind comes when your life is in harmony with true principles and values and in no other way.Stephen R. CoveyThe Author of this QuoteAuthorStephen R.
