Like you, I see golf as a great instrument of business. Getting customers on a course for 4 - 6 hours, with lunch or dinner included, is a great way to discuss business in a much more focused (i.e. no distractions of email, calls, pop-ins at the office) while have a much more relaxed setting. It has been business opportunities in the recent 3 years that have brought me back to the sport.
I started at 12 hitting balls in the backyard with my dad instructing me. My dad was a great golfer, consistently hitting low 80s with a few cracks into the 70s. A good instructor he was not, though he was doing his best to introduce me to the game. And, it worked. I fell in love with it pretty much right away, eventhough I was tremendously stressed when I would play with my dad. As good as he was, I was intimidated by his play and the way he would correct my play. But, when I got my license I was able to play with friends under more ideal conditions.
I played for years but my play lapsed when I was in the navy, kind of hard to find a lot of opportunities play when you are underwater on a submarine. But when I got out I moved to Phoenix, AZ which is a Mecca for golfers. I played quite a bit when I first moved there and found I was improving, but then life caught up with me and I found myself focusing on my wife, later my first son, and a love of endurance training and racing in triathlon.
I didn't play for several years, and had no real interest in playing. Until I was asked to play in a work outing, which was terrifying. I had been (still am, but improving) a habitual slicer, and was more than relieved when the event was canceled. But, the bug bit me again and I started to hit the range and found that I was falling in love with the sport all over again.
I took my first lesson a few weeks ago and walked in with an HCI of ~23, typically shooting between 94 and 104 for 18. In one lesson I realized what I had been doing wrong, and how I had modified my swing to allow me to do those wrong things yet be somewhat productive on the course. In the time since my lesson I have tried to hit the range 2 - 3 times a week and play some local courses. When I connect with a proper swing I have added 20 - 30 yards to my clubs and I can't believe my eyes. When I miss, I seem to be at least be missing straight. All this adds up to the fact that like most golfers I struggle, get frustrated, want to do better, spend my time looking at golf info (clubs, articles, forums, equipment, etc.) in the hopes that I will get better.
If you haven't yet, I would recommend a lesson or two, or three. I have personally realized that going to the range with the wrong swing will not make you better, only more committed to the wrong swing. I am scheduled for another lesson in 2 weeks, and looking forward to seeing if anything I learned in my last lesson has stuck.
