Practice swinging with a baseball bat. The way the bat stands up, levels out, and the timing of how you change directions is very similar to a golf swing.
Flip the driver around and hold it at the hosel. Make swings with the handle of the club and switch back. You want to feel the weight and the arc.
Draw a dot on the center of your clubface. Concentrate on putting that dot on the back of the ball, and you'll make great shots.
To get great results on the golf course, focus on impact and follow-through, not your backswing.
