Perhaps one of the quickest and easiest ways to improve you game is to be conscious about your focus - the more we can associate to our target the better ... as we do this, we become only aware of where we want the ball to go and not allow ourselves to be distracted by any obstacles which may be in the way..  

In terms of process , know the distance to your target - the more exact , the more confident you can be in your club selection.

 Next , picture the shot you would like to hit before you begin your  set up routine.. set up , focusing on feeling comfortable & let the swing happen ... enjoy the result & move on to the next shot.

if you want to lower your scores really quickly then try this test I did with a new client last week.. you  surprise yourself!

from around 80 feet away & 10 feet from the putting surface I instructed the client do choose which club & shot they would feel most comfortable with getting the ball close.

The test was 10 shots we added up the total distance /10 for an average


The client Choose to use his Pitching Wedge.. result  10 shots , total distance 230 feet ,  average 23 feet away


I then suggested he  use his 7 iron...                  result  10 shots , total distance 125 feet ,  average 12.5 feet away

lastly I suggested to use his rescue club (which he had never tried) for this kind of shot &  suggested to me that it was the wrong club & wouldn't work!!

well the result was ...         10 shots    ..   total distance  72 feet .... average of  only  7.2 feet

the learning I got from this (& he did) ...   

practice a few different ways to get the ball close from off the green  - you should have at least 3 ways

discover for YOU which shot statistically WORKs best to lower your scores in this case the one he would not have thought of was  3 times closer than his before "favourite"

Enjoy challenging yourself to  increase your short game skills!

Good luck & Have fun with your Golf!
