I do understand why people are reluctant to take lessons. It is fun to figure things out for yourself and I have seen those guys who have become so depend on their pro that they basic ask how to tie their shoes. Although I really do believe in lessons. After my first lesson I broke 80 for the first time. A year later after my second I went out and made 7 birdies in one round. The most that I had ever had before in a round was maybe 2 or 3. Short game is very important but taking pressure off of it by hitting a lot of greens in regulation helps too. First and foremost I would ask around and find a good pro in your area. I truly do believe that a lot of club pros out there are terrible. I've only had 4 lessons in my life, which is about to change soon, but I would say that 2 were good and 2 were terrible. Looking back at what the guys told me with the bad lessons I can't believe it. Some guys come up with these weird ideas and drills that are more destructive than constructive. So my advice would be to definately get lessons but make sure that it is from someone good that has been recommended to you.
