Oh, there will be a time you will quit kicking yourself, but that miss will become a part of who you are as a person and hunter. Two big ones I had marginal hits on (both lived and I got to see them both again...both bigger, but never another shot), and a couple that have walked out of my life never to be seen again. A couple stands I still sit is where some of this has happened. I relive them every year at least a few dozen times. There will come the day where you will be glad you had the opportunity and missed instead of never having had the opportunity.
