Just my two cents but what do I know.
If you are on the course thinking about specific swing thoughts each time you hit the ball during a round. You are fucked.
Your mind is your worst enemy and when most guys hear some technical swing bullshit. It's a combo for disaster because 95% of guys do not know how to apply most of the shit technical guys throw at them.
There is a lot to the phrase from Happy Gilmore "find your happy place". I am a bigger believer of attitude and mental state. When you are in the zone if you stop and think about where you were at mentally. You will find that your mental state is completely different when you are hacking it up. Separate the two and work on your thoughts. The key is to find your "happy place" and you will find yourself on the winning end more often. But like I said your brain is the biggest obstacle on the course.
I got to the point where it is not possible to be any better. It is simply a matter of my mental state. I have shot 64 in tournaments and a comparison to where I let myself get. My last 2 rounds as a pro I shot an 86 and a nice 84. Problem was I had no confidence in myself and could not channel my thoughts anymore. I had lost it and everything was crashing in around me in my world. I missed my last 7 cuts and ran out of money
I view the majority of guys who give golf lessons as lesson salesmen. It's all about your money and all one of these guys needs to get credibility from an average golfer is mention technical swing terms.
I gave lessons for a short time and it was unreal how fucking stupid people are when it comes to golf and lessons and the reality of what they are doing. You can be told all you want but people I dealt with had jobs, families, etc just don't have the time they need....People think they take a few lessons and magically start shooting lower scores.
And where I am from the most successful lesson pros are the ones who can sound the most technical after watching you hit balls. Because they sure sound like they know what they are talking about
Go play these same lesson pros for money and they are reliable ATM machines.
