This book discusses the brain and nervous system specifically in terms of learning. The brain is so interesting and capable of so much. I do enjoy learning about the brain. However, I do not think this book is meant to be about the science of learning. I do think mastering something is about practice but there are cases when mastery just isn't possible. If I were looking to master something or start something new I might pick up a book like this. This book is not something I'm interested in.
