I think きょうどう is the art of archery, or the mastery of the bow. There's not a lot that I know about this.
As with any discipline, one of the things you need to have in order to become good at it is patience, dedication, and the ability to slow down. When you're able to do this, you're able to see your mistakes in a level-headed manner and focus on the proper form.
My biggest question is if it's hand specific. How does being left handed instead of right handed change the approach?
