Hi, I'm Polina. During the week, I'm a reporter at Fortune Magazine. On Sundays, I'm the author of The Profile. I've read thousands of articles on high-profile figures like Elon Musk, Sheryl Sandberg, Jay-Z, and Harrison Ford. How did they become successful? What qualities do they possess? What are their weaknesses? What makes them tick? We explore all of this & more every Sunday morning.
