https://en.wikipedia.org/wiki/Analysis_paralysisHave a couple of beers and then shoot. What this accomplishes is dulling that tendency to over analyze and let you shoot more for fun. This is just another example of the brain getting in the way of the hand and eye.
I am getting better now with more practice and watch catapult carnage video, "how to shoot a slingshoot in 7 steps". The part where he says let the bands do the job.My problem was always overthinking my shooting form. It doesn't matter what shooting sport, I always try too hard. The one sport I do better at is shooting clay pigeons. They throw the clay pigeon and I instinctively shoot it. I couldn't tell you how I do it. Let us know how you are getting along.
