Today there is a skepticism of any deep, lasting, profound change in a person.
Wisdom today is thought to be accepting internal circumstances rather than changing them. A suggestion that you can change is viewed with suspicion, as a kind of coercion. We are who we are, and we're taught to be proud of it. But people do have a deep longing for change, a widespread and deep-seated dissatisfaction with ourselves. Complacency about our state is common.
