like others here I would suggest joining a club and learning to shoot before buying a bow, but due to financial reasons (and the fact that my local club was only open when I had other things I had to do) I taught myself how to shoot a bow. I started off with a 25lb compound bow then later moved up to a lamanated wood recurve of 60+ lb (can't remember the exsact strength) but due to the fact it was an old 2nd hand bow that hadn't been cared for in years it ended up breaking rather quickly. a couple of years ago however I was walking through my local market and stumbled on a stall that sells air rifles, paint ball stuff and telescopes and noticed they had a few nice recurves and ended up buying a nice fiberglass takedown recurve which is great as it is now easier for me to take it to the fields just outside of my village for some field archery as well as to the dojo where I train (which doubles as a scout's hall) which has some target butts that I can use for practice.
despite not having any formal instruction in the use of the bow I can fire consistantly enough to put around 16 out of 20 arrows into a target the size of a coke can at 25-30 yards, at least on a good day.
eye dominance is very important when useing a bow, which is one place I'm lucky/unlucky. even though I find it more comfortable to shoot holding the bow in my left hand, I'm ambidextrous and both eyes are equely dominant, which makes aiming a bit tricky as both eyes try to focus on the target unless I close one eye (which brings problems in itself such as judging distance)
