Heck, I'm not good, just got real lucky! Well, except when I got caught in the rain with un-sealed wood arrows.....

Something that might help with the slump--form practice. Get the lightest draw weight you own, get a big target (or have a good back-stop), and concentrate on consistency--consistent hold, draw (smooth and controlled), anchor (2 or 3 point anchor works better for me), release (work on relaxing your hand and letting the string push your fingers out of the way), and follow-through. Close your eyes so the target doesn't distract you. Focus on one or two things at a time if you need to. If you can get consistency down, arrcuracy will follow.

Another thing I've noticed myself doing, especially when I'm in a slump or have a difficult shot--I have a tendency to "peep" as soon as I release, trying to see where the arrow is going instead of maintaining focus on the spot--that one really buggers me sometimes.

Don't let it bug you--work on consistency, have fun, and it will work out.
