I tought myself with an acoustic when I was 18 and have been playing since, just for fun at get togethers and such. I grabbed a few basic books, learned some cords, and found some songs I liked and began learning them. After a while it came easy.

My suggestion to you is to get a decent guitar but nothing too expensive just in case you decide it isn't your thing acousitcis my suggestion because it is moreportable (no amp needed). Have fun with it and keep it simple, that is what I do and everyone seems to enjoy it!!! Been playing for 14 years now and all I play is chords, a few intros and some base runs.

If you have any questions give me a shout, I am only a few counties away!!!
