I finally "got it" this last weekend. After shooting a career low 85, I went to the range to try and figure out what I was finally doing right. I basically forgot the last 4 months (just started this summer) of youtube videos and reading I had done and just let my swing do its thing. I hit about 250 balls during that session and now I can hit all my irons 4-9 effortlessly without fear of a shank.
Anyway, I suggest as others have said, try and minimize your thinking and technique and just naturally go out and let your body do its thing during your swing. With that said, you should still have a few good basics established - grip, alignment, ball position.
Find what will work for you. It took me 4 months, but man it feels great once you "get it".
