The belief in self-improvement is a prophecy just as self-fulfilling as the old belief that character could not be changed. People who believe they don’t have to be sedentary or hostile will try to take the steps that get them jogging or make them think twice when trespassed against; people who don’t believe change is possible will indeed remain incapable of change.
I now enjoy, or at least can muddle through, a run. And I love how I feel afterward!
