How to hit the fairway

I spent a lot of years fighting the dreaded slice. I fixed this with one simple swing thought that has helped me to hit the ball straight more often than not. On my back swing, I simply think about not letting my hip turn to the right as I go back. on the downswing, I just let it go and the result is that I hit more fairways than I used to do. If I start hooking the ball a little bit, I stop thinking about the hip turn and just hit the ball.
