Reddit reviews Butch Harmons Playing Lessons

Yes 2 different ways to think about it.

First: wanting something [a well struck ball and a good result] and then not getting it [thin, fat, slice, hook, catching a tree limb] it is just natural to get mad. So, changing what you want is a good way to go about it - change what what to something you can control - [good aim, good setup, choosing the right club, being in the moment] then just watch and see what happens - and use that information to improve. Getting mad at yourself for not aiming is legit - that is just a dumb way to play and you can instantly modify that behavior.

Second: understanding the game itself - no one hits perfect shots all the time. Look how bad Tiger was when he was changing his swing and dealing with his back issues - he was hitting it everywhere, even flubbing chips. Sure, we can be unhappy about our misses, but it has to stay in perspective. The game is not about hitting perfect shots, it is about hitting the fewest shots - understand the game you are playing and act accordingly.

Unfortunately for a long time the PGA has taught the game as a 'here is how you swing' game - I learned a lot from Butch Harmon's Playing Lessons book - it talks strategy about how to play golf - where to aim, how to manage risk, how to go low (when you are on fire) and how to not go high (when you are not hitting it well)
