I've wanted to learn for years and I did actually try when I was about 18/19 but I never had the patience to practice & stick with it, or anyone that I could ask for advice. Hopefully now I have a few mates that play it'll mean I have more incentive to stick at it and improve, plus I'm a bit more patient these days.
More than anything though, I'm 30 next year and learning guitar was always on my 'things to do before I'm 30' list!
