Rehearse impact
I know a lot of golfers who hit it great on the range and then struggle on the course. One of the reasons is that on the range you get feedback from one shot and can immediately try it again with an adjustment. On the course, you don't have that luxury. So one way to remind yourself of what you're trying to achieve is to rehearse the proper impact position.During your next round, address the ball normally, but before you swing, get into the proper impact position (weight on the front foot, shaft leaning forward, head behind the ball). Once you do this, go back to address and then hit your shot, trying to get back to that same impact position.
