About two weeks into climbing, I was fortunate enough to stumble upon this book in one of those give-and-take bookshelves in a local coffee shop. Reading it helped me a lot, way more than any online resource I've found. It will help you come up with a clear plan for improvement and teach you about how to think about climbing. You're gonna have to put in the work at the end of the day - it's not a shortcut by any means. But if you take the advice this book gives seriously, I think you will be surprised by the results. Before you throw money at a coach, consider reading up more.
