I've been lurking on this site for years, and finally decided to join in. I don't have a lot of time to be real active in the forum, but hope I can make some positive contributions.
I've been playing for about 15 years now, but swung my first club when I was 39. I don't play enough in a year to really ingrain anything and didn't want to waste $$ on lessons when I knew I wouldn't be able to follow up with dedicated practice. I've self taught my way down to high 80's/ low 90's, with a lowest round of 83. I also have been known to blow up, but that's getting rarer as I get smarter with taking my medicine after hitting bad shots instead of trying for a miracle.
Anyway, be merciful.
