If you have experience hunting with other weapons, then "trad" bow hunting is not that different.
Assuming you are shooting without the aid of a sighting device, the actual shot taken at game demands a bit more from you in the form of mental discipline. The physical part is taken care of through dedicated pratice...but it all means nothing if you don`t use your brain in harmony with all that practice.
Believe it or not, SMALL GAME hunting was MY best teacher. More shot opportunities and when you can center punch a squirrel it bolsters confidence like nothing else.
My tip would be hunt squirrels or rabbits whenever you can...nothing teaches shot discipline on game animals like shooting at game animals. :D
