Merrick Rosenberg, creator of the DISC personality system, dives deep into personality intelligence. He argues that many personality tests limit our growth by boxing us into static labels. Instead, he encourages mastering all personality styles, likening them to bird archetypes: eagle, parrot, dove, and owl. Merrick shares insights on reading others, meeting their needs, and becoming a chameleon in communication. Plus, he offers practical steps for gradual behavioral change, emphasizing the long-term journey toward authenticity and flexibility in interactions.
