Playing the ball too far forward or letting the clubhead get ahead of the hands at impact adds loft to the club. The resulting shot flies too high, robbing distance and your hope of positioning the ball properly. If trajectory is a problem, check your hand and ball positions. Hands should be even with or a hair ahead of the ball at address, no more. Ball position should be no farther forward than your left heel with the irons, not past the left instep with woods.
Some players like to play all their shots from the left heel, which is okay.
Experiment with ball and hand positions until you're achieving maximum distance in the air and minimum roll on the ground. Understanding what causes different trajectories also will teach you valuable lessons about playing higher or lower than normal shots when trouble situations demand them.
