Full swing:
I learned the 'toe up, toe up' drill years ago and still use it when I get out of sync/sequence. Take the club back until the shaft is parallel to the ground, the toe of the club should be pointing straight up. Next, swing the club forward stopping when the shaft is again parallel with the ground and the toe should be pointing up. I use this drill when warming up, sometimes hitting balls, and on the course. It's a great way to reinforce the positions you need for the "slot'.
Putting:
Drop a few balls about 10 feet from a hole. When you strike each putt, don't lift your head but say out loud how the putt felt, either short, long or good. Don't look up until you think the ball has reached the hole. A great drill I learned 25+ years ago for developing feel.
Chipping:
Look at the triangle formed by your arms and shoulders. Don't break your triangle and hit down on the ball.
