Who is your go to for learning about / training on the mental side of the game?
I've now read "Putting Out Of Your Mind" and "Next Shot is Best Shot" by Dr. Rotella, "Be a Player" by Pia Neilson and Lynn Marriott, and "Fearless Golf" by Gio Valente. All have been good for different aspects, all have overlaps too.
What are your favorites and/or recommendations?
