Here is a drill you should start doing asap to learn how and why the club swings inside out at the ball instead of coming over the top. Learning to swing inside out gets you half of a draw or straight shots. This coupled with the release creates direct contact instead of cutting across the ball putting slice spin on your shots.
You need to start doing this drill right away as it takes a little while to change how you have been swinging in the past. Over time, you will train yourself to swing inside out at the ball forever.
