like stated above. shoot, shoot, shoot. form is important for consistency but everyone has to do what works for them so once you find a way that fits you get consistent. personally I like shooting the asbell way. high wrist, canted bow. shoot every day. with the right set up and lots of practice you don't need to wait two years. you could be ready by late archery for sure. Hell even early if you dedicate yourself to it.
(full disclosure, I switched to compound 3 years ago but that doesn't take away from the fact that I shot trad for over 15 years before that. all my "biggest deer" are still from my recurve days.)
