Adjust your grip to make the ball curve differently by setting the clubface more closed if you tend to slice the ball.
Get a feel for how to hit the ball by breaking it down into three parts. First, swing with your right foot back, then your left, and finally, with both feet together.
Choking down on your grip almost to the end creates a counterbalance, making it easier to control the club. This will help you hit the ball farther.
