Unfortunately, not matter how hard we try, we are not masters of our fate.
The world is a random place, sometimes it is beautiful, sometimes it is cruel, but the one thing you can be certain, is that your plans will not be respected.
So what can we do?
The best way to live and stay sane in a world that is inherently chaotic, is to be comfortable letting the arrow fly.
So practice shooting, choose the best bow, find the best conditions and time, but once you let you arrow fly, you have to know that there is nothing else you can do.
The target might move, causing you to miss, or a sudden wind may take it off course. This is none of your concern, as you have already done your part.
Remember, your responsibility ends the moment you let go, so you should not worry about a flying arrow, just concentrate on your next shot.
