Read this excerpt from Frida Kahlo by Hedda Garza. Kahlo brusquely informed Rivera that she wanted him to tell her the unvarnished truth about her work. If she could not earn her living as an artist, she announced, she would take up some other profession to help her parents. "I want you to tell me if I am a good enough artist to make it worthwhile to go on."

Kahlo unwrapped three of her portraits and waited as Rivera studied them. In a few minutes, he informed her that she was indeed an authentic artist.
