I find Lewis's blog posts to be rather long-winded, but this book was just about the perfect length. Reading it reminded me to study more frequently! Hopefully that motivation will continue even now that I'm done with the book. It's also inspired me to go forth with finding an online teacher and language partner, as he says speaking with native speakers is the most productive way of learning. I recommended this book to a friend who said she wishes she had learned Japanese at a younger age, because I think she is exactly Lewis's target audience. Well worth a read for any language learner.
