Form..form..and form Joe.
Just figure out what works and stay consistent.
^^^^ Yea, that. ^^^^
And baby steps. For me, anyway, I had to take baby steps working back to what I think of as a normal hunting distance. For several weeks I hardly shot past 10 yards. 5 yard jumps with a trad bow felt more like 15 with a compound. Something that helped me with arrow selection was a 3Rivers arrow test pack. It comes with one shaft in 3 different spines, you can have them cut them or leave them uncut and you cut them down. I paired that with a field point test kit to find the arrow/tip weight that worked best for my bow.
My only other advice, since I'm still pretty new at it, is try new stuff to see what works best for you. In trad archery, gloves and tabs and silencers etc... are pretty cheap. I started with a glove, then tried a cheap tab, then bought a Black Widow tab. Even through all of that, I still have a whopping total of about $35 invested in trying those items. I just ordered a new string for my bow and it was $17. A "hush kit" from Mountain Muffler Strings that I ordered was $12 and it's enough to do 2 bows/strings.
If you're the type who learns well from watching videos, check out the following folks on YouTube: Joel Turner, Clay Hayes, The Push Archery, Aron Snyder, Tom Clum. I've picked up a ton of helpful information from those guys, and a few others, on everything from shooting form to tuning to shot process.
