Everyone wants to hit a good long drive, and in most cases, a good hole starts with a good drive. But to hit a really great drive off the tee, you need to start preparing even before you address the ball. It's important that you develop a pre-shot routine that includes positive thoughts and visualization. What does that mean? Try standing behind the ball before you hit, and as you look down the fairway, visualize the target and imagine a good shot going right at the target. Next, when you do address the ball, you should release any tension that has built up in your body. You can do this by waggling the club and taking a good, deep breath. Also, make sure you're comfortable with your alignment before you hit. Finally, take the clubhead back low and slow. And as you do, you can say a little prayer: Please, let me hit this one straight! You just might surprise yourself, and your partners!
So the only way I can drive longer is to pray to god on the back swing lol.. Don't you just love internet advice.
