As you live your values, your sense of identity, integrity, control, and inner-directedness will infuse you with both exhilaration and peace. You will define yourself from within, rather than by people's opinions or by comparisons to others.
Stephen CoveyIn a very real sense, there are only two roles in organisations: customers and suppliers. Everybody functions simultaneously in both roles, whether inside or outside the organisation the essence of good business, therefore, is the quality of the relationship between customer and supplier.
Stephen CoveyIf you are an effective manager of your self, your discipline comes from within; it is a function of your independent will.
