I have some machining tools and experience.....and 30+ yrs of gun (and other precision) work behind me. I can spec out a device, and have blueprinted some stuff, and can fret a measurement as much as the next guy. I can also take something that isnt 'quite' right and shoot it and have fun and have learned to say 'it is adequate'. Giving myself permission not to have to 'fix' everything (yes, I am a frustrated OC perfectionist) has been 'liberating'. I am, without a doubt, the biggest handicap any of my firearms have.
Keep making those 'satisfying' shots, take some you might not make and learn what she does. Close doesnt always just count in horseshoes......a difficult shot that comes mighty close encourages me to bear down and try harder.
Above all, have fun, and dont sweat the small stuff........in the greater scheme of things, its all small stuff.
