RE: Rushing the shot !!!
Ok, this might seem a little weird but I had the same problem and it worked for me. Tape a small piece of paper on the inside of one of your limbs and write something on it to slow you down. Could be something as simple as RELAX, or SLOW...it helped me to the point I dont need it anymore. Also dont forget to aim at the bottom of the deer....missed many cause I failed to compensate for them jumping the string.
