Trouble scoring low all of a sudden?

Have a consistent pre-shot routine? Swing thought?

If your swing isn't the issue as your claiming, it could be a mental issue. You should have the utmost confidence in your swing so that when you stand over the ball on the course, all you're focusing on is results. This is where the pre-shot routine and consistent swing thought helps as well. It's just another swing once you're standing over the ball. You've hit it hundreds of times and you know you can hit it.

For instance, my swing thought is "smooth swing." No matter what I'm doing. Hitting a draw, fade, pitch, chip, putt - same swing thought for all of them. "Smooth swing."

Then again, because I don't know you and haven't seen you swing, I could be way off the mark here.

yea I've been told that alot recently and that's why I brought it up. They say your swing is different on the course etc. ill try to make an effort to play more i am traveling to LA today from SF and I'm playing 1 round on Thursday 5:30 AM and one Friday 7:30 am, ill let you guys know how it goes!

Your pre-shot routine and swing thought needs to be what is best for you. I don't think you spend too much time of the range. A lot of Korean golfers learn the game indoors hitting off mats into nets. You would probably benefit from treating each shot on the range like its out on the course. Step back, pick a target, and go through your routine. Too many golfers just stand there in one spot and hit balls over and over for no reason. Of course you can hit the ball well when you do that. It's a lot easier to get into a repeatable swing when you hit a ball every 15-20 seconds. But on the course, you can go for lengthy time periods between shots, so practicing that way doesn't help.

For example, take the local 9 hole course that I walk frequently. I hit driver off the first tee, but don't hit it again until the 4th tee. That's a long time between swings. So I need to be able to stand on the tee box and go into a routine so I can try and repeat the process as close as possible each time.

Practice. Do what feels natural and comfortable. Then make a point to do it every time. If 2 practice swings makes you feel confident, take 2 swings. It's that simple. I'm not sure why you're feeling rushed. Think of Ernie Els and his shuffle as he settles his weight. Or Matt Kuchar and how he hovers over the ball before taking it back. Or Jason Dufner and his waggles. Some guys have a forward press with their hands that acts as their trigger.

And your swing thought could be anything that gives you a certain image or feeling. Smooth Swing for me makes me think of tempo. There are an infinite amount of possibilities.
