Benny Lewis, who speaks over ten languages all self-taught runs the largest language-learning blog in the world, Fluent In 3 Months. Lewis is a full-time "language hacker," someone who devotes all of his time to finding better, faster, and more efficient ways to learn languages. Fluent in 3 Months: How Anyone at Any Age Can Learn to Speak Any Language from Anywhere in the World is a new blueprint for fast language learning. Lewis argues that you don't need a great memory or "the language gene" to learn a language quickly, and debunks a number of long-held beliefs, such as adults not being as good of language learners as children."
