While Mark Twain was a prolific writer and had strong opinions about literature, there is no record of him making that statement. He did, however, say many interesting things about reading, including:
* "The man who does not read good books has no advantage over the man who cannot read them."
* "The secret to getting ahead is getting started." (Though this is often applied to reading, it's not specifically about literature.)
* "The best way to cheer yourself up is to try to cheer somebody else up." (Also not specifically about reading, but related to empathy and understanding, which are crucial to enjoying literature.)
Mark Twain was a champion of good literature and believed in the power of reading to enrich lives. He encouraged everyone to read and experience the world through stories.
