A Correspondence of Renaissance musicians Book

This book contains a great deal of information that will undoubtedly be very beneficial to many people. I did learn about several topics related in some fashion to developing mental toughness. I would have preferred the authors to include 'more meat and less gravy' as it were. That in no way is to imply that this is not a well-written, or informative book. It certainly is both of these. But as is the case with so many "Self Help" and "Management" books, this one expended a great deal of effort working it's way to the crux of the matter. Even so, for anyone at the first stages of dipping their toes into the shallow end of the pool, this book is a really good beginning point. I was hoping for something that more vigorously addressed the end of the pool a bit closer to the high dive board.
