I agree, only take shots you know you will make. That said good season. My first two seasons were spent watching deer. I always found a way to not get into a shooting position. Then my third year I harvested a 7 point buck on public land and it was Jan to boot. I was very cold but that day I made no mistakes. Every year since I have harvested no less than 2 deer per year. I shot a Pope&Young WT and a P&Y Antelope last year so it seems in bow hunting success begets success. Keep at it but don' t take low percentage shots. You should buy a " Balaclava" (?spelling) they are warm and can be used in many ways. With mine I can slide the part covering my nose and mouth down with my thumb as I complete my draw cycle. Then I just put my kisser button in the corner of my mouth and shoot. Hope this helps!
