Isn't there a tennis player who, after not managing a shot during training several times, would just stop, because he "didn't want to practice it wrong"?
There is perhaps a small amount of truth in that, but generally, hours put in = result. You rarely notice it during the practice, that's the thing. Over Christmas I started practicing the move for Greg Wilson's "boomerang card of death". Cards went everywhere, cards bent, my hands ached, and although I'd go through a few sweet spots I'd often end half an hour's practice with a sore thumb and feeling just as far away as ever. I'd practice altering the grip, changing the position of the thumb and the pressure etc, sometimes one way worked then the next minute it didn't...
But about a week ago I picked up the deck, and suddenly I was doing it. Not only that, but my hand felt pretty relaxed doing it. I could vary the height of the arc as the card spun out, and catch it 9 times out of 10. I'm now at about 7 out of 10 success rate at launching it from behind my back and catching it in front.
So I don't really believe in the "don't practice it wrong" thing. Your body is cleverer than you think, and you will be subconsciously picking up on all the times it doesn't go right, and the times it does, and what you're doing differently. But I expect mostly, your body is getting used to the movement, strengthening muscles and improving coordination, so that even if the end result during practice is far from perfect, you are actually one step closer each time. Then, when it all comes together, it will hopefully just "click."
I'm now practicing the windmill move by Lennart Green (as taught by Matthew J. Dowden on the excellent DVD "Party Animals"), and guess what? It's still feeling awkward every time...
