Hockey Tough by Dr. Saul Miller was a pretty interesting read. It's geared more towards a young player looking to get an edge on the path to a professional career in hockey, but it's loaded with great information and transferrable skills you can use in any facet of life that requires confidence and critical thinking.
I may have to check out that Play Better Hockey book.
+1 for Hockey Tough
I don't want to sound dramatic, but this book changed my life. The relaxation and positive thinking techniques that Dr. Miller talks about have made me successful on and off the ice.
A good one I'm reading right now is Zamboni Rodeo by Jason Cohen. The author follows the Austin Ice Bats (a "AA" Prosfessional team at the time) for a season and chronicles the success of professional hockey in a really unlikely place. The players don't make very much and are either at the end of their careers or trying to jumpstart their pro career; either way it's not a very glamourous lifestyle and they are truly playing for the love of the game.
Laura Stamm's book was suggested to me by someone on this site. I really like it- the pictures were enough of a visual for me but if you're like Jarick, you might want to supplement it with youtube videos.
I also have the conditioning book with the dvd. I haven't used it all that much but I like it so far- it'd be nice if it included more excercises that you could do without all of that specialized equipment though. I'm sure if you're creative enough and have the material that you could improvise pretty easily.
Obviously it's been brought up, but I'll say it again, Hockey Tough. It improved my game as soon as I started using its techniques. It's to great to look over before a big tryout or to use psyching yourself up for an important game.
