I'm still waiting for it to all come together, and I have been doing this a long time. If I concentrate, I'm fine, but if I lose just a little concentration, things go downhill fast. Byron Ferguson is in no danger from me, but I shoot pretty well most of the time.
The concept of shooting a longbow (or recurve, for that matter) is simple; pick a spot, concentrate, anchor, release. However, simple isn't always easy. Maybe that is why we enjoy it so much; if it was easy, it might get boring, and the constant challenge to do everything right keeps it interesting.
