You're right about us all striving for perfection. And although it will never happen we can continue to practice until we get better and better. But remember, only perfect practice makes perfect.
One thing that Nomercy made me think of is: does your bow rock back as you draw? Try pointing at your target and start your draw. Does your bow rock up or down? It could be that your limbs are not balanced. One or the other may have to be adjusted to give you a smooth draw without any rock.
