I dig that quote.

One of the things my grandfather drilled into me that guns are a responsibility, not just a tool. You mess up with a hammer, you bust a thumb. You mess up with a rifle, someone can die.

Marksmanship, and the process of developing it, really is about self control. On so many levels, not just the obvious. Like, breathing. The way you do it, and when you hold it, syncing it up to your aim, then the control of how you squeeze the trigger.

If you can’t control yourself with shooting, there’s a pretty good chance you’ll have trouble in other ways too. Conversely, shooting helps develop that awareness, the patience and self reflection, that makes for a solid person in general. Not that there aren’t other ways to develop that, there are. But it’s a pretty damn good option
