Funny, I'm always in the minority on the lessons thing ... just seems to me there are so many online resources (youtube), everybody's phone has a video camera on it nowdays to video your swing, golf channel with instructional shows on every night, and discussion boards like this ... that it's MUCH EASIER than it ever was to figure out how to swing a golf club properly than it ever was in the past. Lessons are fine, but so many people use them as a crutch & don't put in the effort to try and figure it out on their own (my wife is a perfect example of this).
Golf is hard. If you want to improve, you have to take the initiative to try and figure it out using whatever resources are available to you.
Right there with you. Never had a lesson and don't ever want one, although seriously considered it over the past few months.
I'm a total feel player, don't understand the mechanics, just know what my body feels like when I make a good swing. When my buddies make a bad swing and start to explain it's because their hands were turned a certain way or some other technical rationale, I start to get tired head.
A few keys I use: if I hit it left, it's usually cuz my hands were faster than my body, opposite if I hit it right. If I hit it fat, usually cuz I was moving during the swing, typically my head and if I hit it thin it's cuz I lifted up. That's about it. Often said I'm the least-informed 5 cap in America (when I was a 5, long time ago now, it seems), with probably the ugliest swing.
Different strokes I guess.
