The self-renewing person is highly motivated. The walls that hem us in as we grow older forms channels of least resistance. If we stay in the channels, all is easy. To get out requires some extra drive, enthusiasm or energy.
Everyone has noted the abundant resources of energy that seem available to those who enjoy what they are doing or find meaning in what they are doing. Self-renewing people know that if they have no great conviction about what they are doing they had better find something that they can have great conviction about. All of us cannot spend all of our time pursuing or deepest convictions. But all of us, either in our careers or as part-time activities, should be doing something about which we care deeply.
John Gardner, Self-Renewal
