Anyone who hasn't heard of or read Rotellas stuff, go and get it now! I am a new member here but teach golf in Cyprus with a strong focus on the mental game. I don't agree that you should get swing right before worrying about mental game as I've read a few times already on this site.
The way you approach and think about the game will have a large impact on how you develop your game and swing. Mechanics and mental game work hand in hand so start now. Most people will have no idea what they are missing. Contact me for more recommendations if you like.
