Your initial golf shot is you’re most important golf shot in my estimation. It is sort of like first down in football. If you are second down and twenty every time you get the ball you are going to have a long afternoon.
          If you’re having trouble during a round of golf with hitting your golf driver in the fairway the n drop down to your three woods immediately. Maybe after some success with your three woods you will gain your confidence back to try your driver again. The little bit  of distance you will loose by hitting your three wood will be more than compensated by being on the short grass in the fairway. Work out any problems with your driver in practice not on the golf course.
The first thing you need to understand about a drive is that the length is probably doing you the most harm. A golf swing is very similar to a group of skaters turning in a circle or a group of soldiers marching in a circle. The outside skater or individuals will have to move that much faster than the rest of the line to keep up. Sure the longer the  driver the faster the club head will travel in theory, but equally the harder it will be to square the club face at impact thus causing that dreaded slice off the fairway.
          To square the golf club up at impact, you need to start rolling your forearms over earlier. Why, because the golf club head is further away from you. If you are having trouble squaring up the club face first try choking up a little on the golf club.
          Everyone is raving about the hybrid woods that are replacing three irons. Golfers rave about how easy the hybrids are to hit. The heads are small and have a low center of gravity. In contrast the new drivers have a head the size of a basketball and golfers wonder why they can not square it up.
Some golfers try to keep their head still or over the top of the golf ball. To make a full turn on a swing with your driver your head might move a little towards your back foot. That is fine if not desired. You need to be well behind the golf ball at impact. One should have a straight line from the front shoulder to the ball at impact.
Some golfers tend to hit their driver out on the toe. Use some face tape on your driver and witness for yourself where you are making contact with the face of your driver. Usually the best place to make contact is high on the face and just a little inside of center. Different drivers have difference centers of gravity.
