Not sure I could limit what success I've had, as sparce as some might consider it, to one thing but if I had to pick it would be immersing myself into anything and everything traditional archery by reading, listening, and experimenting. Some things work, some don't for me, but I keep an open mind. I picked up trad again after a 20 year hiatus and feel very lucky to be enjoying the accuracy I am this quickly. The threads and videos here, posts by others who were struggling, and the responses by the knowledgeable archers have often proven applicable, in whole or in part, to problems I may be having at the time. There's not much pertaining to form or tuning here on TradGang that I haven't read in the past few months and learning the tuning process for myself instead of having to take my rig to a shop all the time has given me a much broader working knowledge and the ability to recognize flaws and correct myself a lot quicker.
