You walk to the 8th tee after making a 6 and proceed to swing too hard at the next tee shot. It's a never-ending cycle. Stopping the cycle is simple. As golfers, we can't afford to throw shots away by leaving the ball in the bunker a second time. One swing from the bunker needs to suffice.
Most amateurs fear the sand shot for various reasons.
You may make uncomfortable looking swings to eject the ball from the trap. Hit it thin into the lip and the ball rolls back to your feet again. Stick the club into the sand and the ball doesn't have enough momentum to carry out of the bunker. You want to keep the lower body quiet during the swing. Open the face of your sand or lob wedge until the scoring lines on the face are pointing at the target.
