I always start the season at 3 yards with my eyes closed to work on my release.
Then open my eyes and work on follow through.
Then work out to longer distances and practice at 10 yards beyond my maximum effective range (which is getting harder every year since my property isn't long enough now!).
Concentrate on one element of form at a time. (Each day focus on a different problem, not all of them every day.)
Treat every arrow as an individual w/o regard to the one before or after it, and remember "pratice doesn't make perfect, perfect practice makes perfect"!
