Science trivia: Psychologists now generally agree that the key to change is to create an emotional stimulus; not because people are stupid, but because the human brain is designed to use logic to support our emotional beliefs, not change them. So what you want is an emotional rationale to change, concrete data to back up your progress, and a supportive environment for the new you. Keep in mind that none of this is a breakthrough – politicians have been doing it since the days of Pericles.
