Assessment first, then a pipe and scotch while devising a remedy.
1) Did the animal jump the string? If not, what did I do wrong? I have total confidence that when I hit my anchors, pick a spot, and expand through the shot, the arrow will go where I look. A few possible errors to correct makes the mind focus on a few simple remedies, instead of panicking.
2) Smoke and beverages help the mind relax, keeping me from blowing the miss out of proportion, which could turn it into a nasty gremlin for a long time. I prefer English blends out of a custom pipe my brother gifted to me. (not to mention that he happens to be the maker). A glass of Ardbeg finishes the healing process nicely.
