"People undergo several sequential steps in maturing from infancy including childhood, adolescences, young adulthood, middle age, and old age. Each stage presents distinct challenges that require a person to amend how they think and act. The motive for seeking significant change in a person’s manner of perceiving the world and behaving vary. Alteration of person’s mindset can commence with a growing sense of awareness that a person is dissatisfied with an aspect of his or her life, which cause a person consciously to consider amending their lifestyle."
