Gain confidence by setting specific target for every shot
Pick out a very specific target for every shot that you hit. When you have a specific target in mind as you swing, you will be far more likely to stay committed to the swing at hand. Indecision is a sure sign of doubt in your game.
It doesn't matter what kind of shot you are hitting. It is always important to have a target picked out before you take your stance, so rather than aiming for the fairway in general, pick out a specific target in the distance that you can use to guide your swing. You will likely then notice that there is more confidence and commitment behind your swings.
Before hitting any shot on the course, you are going to be faced with a series of choices. Which club are you going to hit? What are you going to use as your target for the shot? Are you going to try to hit the ball higher or lower than usual?
These and many more questions will need to be answered during the planning phase prior to taking your stance.
As you work through this process, one of the most important things you can do is to keep in mind the strengths that you have as a golfer.
By playing to your strengths -- and away from your weaknesses -- you can achieve better outcomes in the end.
It is tempting to pretend that you don't have any weaknesses in your game, but that simply isn't true for any golfer in the world.
Even the best players in the game have weaknesses that they try to avoid whenever possible.
It would be great to be able to hit any shot at any time depending on what the course throws your way, but that simply isn't a skill that you are likely to possess.
Don't fall into the trap of trying shots you really can't execute just because you want to prove that you can do it.
