Personality Intelligence: Master the Art of Being You

by Merrick Rosenberg

For thousands of years, personality types have offered fixed descriptions of who we are. In Personality Intelligence, award-winning author and personality expert Merrick Rosenberg—also known as the Bird Guy—takes it further and shows us how we can develop our personalities to become our best selves.

He introduces the idea that we can all advance through the four levels of Personality Intelligence—from struggling to express our natural talents to becoming adaptable Chameleons who are wildly successful at everything they do.

Through humorous and relatable fables, celebrity stories, and four subtly-named characters—Dawn Eagleton, Ian Parrotti, Scarlett Doveridge, and Carter Barnowl—Personality Intelligence provides a lens through which readers can clearly view their past, present, and potential selves.
