Golf is a game you play for fun and socializing which develops your coordination, visualization, focus, self esteem, strategy, health also enhancing brain functions.  
I personally recommend taking lessons and practice to develop these skills.  I have found that practicing bad stroking is not efficient and frustrating.  
If you need a good teaching pro, I recommend Matt & Jarod at Magnolia Greens Golf Course.  If you need help concentrating and visualizing, contact me as that is a portion of what I teach.
