I' m in my third year bowhunting myself, and have yet to take one.
I think that if you' re seeing deer, not getting busted, and not missing them all the time or wounding them and not being able to recover them, then you' re doing ok.

Don' t get impatient and take a bad shot.
I' m proud to say that I' ve passed on 3 shot opportunities because they were poor angles, too much stuff in the way, or the deer was aware of me and would likely jump the string.

Ted Nugent said it best:
Don' t be afraid to let your bow down and let him walk.
The perfect moment will come.
