RE: Rushing the shot !!!
Keep in mind you are working in a compressed time frame. What I mean simply is 1 minute seems like 10 seconds. 2 minutes seems like 15 seconds...You actually have MUCH longer than it seems like. From start to finish involves more time than you realize. If you are like me, I always think "Hurry, you have to shoot quickly before the deer busts you and gets away!!" I HATE when deer "get away."
There are many ways to combat this syndrome, but experience is the best. Keep missing and you'll grow tired of it and eventually will FORCE yourself to relax. Close your eyes. Yes, close your eyes. Relax. Breathe deeply, in the nose, out the mouth....for a cycle of 5....which is roughly 20 seconds......It will seem like an ETERNITY, but remember the compressed time frame we spoke of.
Confidence is also high on the list. You must be confident, almost to the point of being arrogant, that you are NOT GOING TO MISS. Know it, know it in your heart that you are gonna center punch that rascal.
Lastly, even though you must be cocky and arrogant, don't put too much pressure on yourself. The more pressure you lay on yourself the more likely you are to miss.
OK, one more lastly......Don't shoot every deer that walks past. Let a few pass, and watch them. Even draw on them, but DON'T shoot....What you are doing is "tricking" yourself and telling your brain that YOU are in control of the shot, not your brain. The more deer you let walk the more calm you will be when you do shoot.
Oh, and don't forget to have fun. That's why we do it anyway.
