The only time we see players hitting the golf ball off the toe of an iron with a 4 1/2 inch long face, or a driver that is as big as a toaster, is when they are just taking up the game, and are trying to figure it out on their own by whacking at balls at random. Get a lesson from a qualified PGA Professional on basic fundamentals. Develop a simple routine that includes proper setup, ball position, proximity to the ball, and an understanding of basic balance, timing, and rhythm.
Generally, we see them going at it way too hard and out of control with independent hands and arms, and standing way too far from the ball because someone told them to keep their arm straight. Get closer to the ball, swing smoother, practice, practice! practice!!!! Have fun learning the game. Those random off-center strikes will be a thing of the past.
