Tests like the Myers-Briggs or Enneagram are not only unscientific but are holding you back. There's no such thing as a personality 'type', or a 'real you' that can only be unearthed through self-discovery. Instead, your personality is something you can build: rather than being trapped in unresolved traumas, you can build your identity to serve the future you desire. In Personality Isn't Permanent, Dr. Hardy draws on psychological research to demolish the popular misconception that personality - a person's consistent attitudes and behaviours - is innate and unchanging.
