"Everything Is Fcked: A Book About Hope" and "The Subtle Art of Not Giving a Fck" are two separate books by Mark Manson, though the query groups them together. "The Subtle Art of Not Giving a Fck" focuses on individual problems by challenging the pursuit of happiness and encouraging people to accept negative experiences and choose their struggles. "Everything Is Fcked" addresses the problems of the modern world, examining anxiety and the decline of hope by dissecting topics like politics, religion, and technology from a place of hopelessness to build hope.
