Some personalized instruction at a bow shop sounds like an excellent idea.
As others have mentioned, it depends on your total set-up. With a compound bow every single details must be properly matched and accounted for. In a sense bow set up is alot like fitting a shotgun, in that you fit the weapon to the user's size, shape and shooting characteristics.
Release aid or finger release also makes a huge difference. Generally speaking if you finger release then you will have to cant the bow, this makes multiple pin set-up very problematic. In contrast, when shooting release style the goal is hold the bow perfectly vertical, and very loosely - others have suggested a yoke/bowsling - this makes a proper hold very easy. For finger release shooters I tend to think that a single pin (cheater) is ok but in practice you are closer to an instictive style of shooting.
Instinctive shooting is great, but requires a tremendous amount of regular practice to maintain proficiency. I shoot both styles, and have for decades. I can take out my release aid, pin and peep compound bow in the late summer/early fall and within a few minutes be keeping ten arrows on a paper plate at anywhere up to 50 yards (I have 20, 30 and 50 yard pins.) At twenty yards the group is so tight I will purposely open it up to avoid ruining fletching. While I'd never shoot a deer at 50 yards, for elk sometimes this is a close as you might get.
Shooting a compound bow in this style is alot like a golf swing - it's all form and follow-through. Do everything with mechanical consistency and the results flow almost automatically. After that it's just some practice with akward shooting positions (sitting, kneeling, etc) to learn how to compensate for their effect on your shot.
Shooting all summer with my recurve I can probably keep all ten on the plate at twenty yards, at thirty yards it's about 6 out of ten - assuming I've been practicing. Take a month off and maybe I'll hit that 30 yard plate the first time, maybe not until the tenth time... Some days you're hot, some days you're not.
