I started seeing an instructor last week. After the initial swing analysis, he gave me a couple things to work on. Working on take a way and swing plane. Went back for lesson 1 and the over the top was way better. But for some reason, whatever I did to correct the over the top, caused me to block everything right. I NEVER hit irons right. After researching it, it seems obvious that my swing plane is too flat from over compensating trying to stop the over the top.
I recommend finding an instructor that knows what they're doing and working with them.
You're unlikely going to solve this stuff on your own, and you're going to create a lot of bad habits and ingrain them the longer you proceed.
You likely haven't made any lasting changes in "the past week." Certainly not to the point where you can move on to something else or go "back to the drawing board."
This is a moment of truth. The way you react to this will have a dramatic effect on the way the rest of your golf "career" plays out.
