Is it possible to change your personality? Many of us may have thought about it, but journalist and staff writer at The Atlantic, Olga Khazan, actually did it.

After spending a year intensively researching the science of personality change, she applied that science to herself. She wrote about her experience in her new book, Me, But Better: The Science and Promise of Personality Change.
