Wayyyy to many swing thoughts and only read the paragraph after address. Most great players only have 1-3 swing thoughts at the max. Don't think about it so much an just get the ball in the hole
This is true. Read Bob Rotella's "Golf is not a game of Perfect" --- did wonders for my on-course game.
On the range, have all the swing thoughts you want. You are there to work things out. Just don't take that crap with you on the course. During a round, your only thought should be the target, then grip it an rip it.
The hardest thing for me lately is trusting that my weight shift/turn will put my hands at the correct impact position, without me doing anything consciously. My best shots are coming when i just get to the top, begin the downswing and forget my hands are even there. I just turn and try to trust my pivot will do the job. This creates the most lag.
The correct golf swing is all about lag... get rid of tension, light grip pressure, correct posture at adress, and using your arms/hands consciously as little as possible.
