I skimmed the thread so I do not know if it has been said yet but more than anything I think it is essential to focus on the hit, make sure you are hitting it (or snapping the disc if you prefer) on every throw. From your drive off the tee to your midrange approach to even your long putts. Locate that hit every time. Everything else will fall into place much easier once you do.
To work on this, find the hammer pound drills (also called the incomplete secret technique or something like that, should be in the technique sticky) and start from a standstill or one step, then work your way up. To me, being able to locate the hit is like a pitcher bringing his stuff or control to the mound.
