A few years ago, while researching for an epic fantasy novel, I took archery lessons. I thought if my characters were archers, I'd better learn something about the art of bow and arrow in order to write with some authenticity.
I learned enough to know I would never be a great archer, but I enjoy the practice and the thrill of hitting the targets.
More importantly, I learned that archery is a great metaphor for life.
Once the arrow is loosed, you have no influence over it anymore. What you do have control over is how you hold the bow, how you position the arrow, and the strength and alignment of your body in the draw and the release.
I have a novel out with several agents. I've loosed that arrow. Nothing I do now can influence its trajectory.
There is something strangely comforting and freeing about this.
