Sure it's worth it. I've been doing it for 35 years now; shooting and bow hunting. How much experience do you need? Well, I would guess that all of us "shooters" started at some time with NO experience per se. You learn as you go.

I would suggest to you that you patronize a local bow shop (pro-shop, that is). Get measured for the correct draw length (most important) and find the poundage you can draw. Don't get carried away on the draw weight. It's hard to learn how to shoot a bow if you are struggling with it. They are adjustable. And make sure it's adjustable for draw length as well.

I would suggest buying a decent used outfit, but not knowing what you NEED it's hard to suggest anything specific. And it's usually cheaper in the long run to have the proper help in choosing gear. Try to shoot a lot of bows and find what fits you (draw length and weight)and what feels good to you. If it's something beyond your budget right now then keep saving. Don't rush into something.
