When you have deer at a distance to you or deer you do not want to take, (practice on them). Draw, look at the spot you want, put your pin on it and HOLD. After a few seconds let down, you have to get use to the feeling of being at full draw on an animal. It does not matter if the deer is at 100 yards do this every chance you get and the fever will supside eventually.
Good luck and just breathe.
