As a child I wanted to be a shop teacher. I think I would have been good at it. later in life I found out that I'm a pretty good instructor.
I did try my hand at being a cop and was good at that, but I ran into laws that were sexist and tied my hands one night to force me to remove the victim of abuse out of his home and allow the female to stay. That didn't sit right with me. She freely admitted that she was the abuser and there was nothing I could do about it as the law was written. I'm not the most PC person on the planet and politics came into play later in my career. I wanted to be a cop not a politician so I resigned and moved on. I went into industry and retired from that.
When I have the time today I am a teacher of sorts but not in shop. But it's at my leisure and my choice of students. I tutor some folks one on one in handgun safety and shooting and certify them for their CCW permits. Shooting has been a love of mine since I was a teenager and I get to combine that with teaching. I'd never be able to make a living doing it but it makes me happy to see good folks able to be societies sheepdogs should they want to take on that role. But at the very least they are able to protect themselves and their loved ones and do it safely. I have nephews that I "gun proofed" as children decades ago to make them safe around firearms and they remember that to this day. I also shoot competition but due to age can't move as fast as I should be able to to be a top competitor*, but I enjoy giving tips to those who want them. I enjoy seeing them use them and passing me by as they climb in the rankings. I'm also the guy with the tools to maybe fix a firearm so that they can get back into competition.
*Think Biathlon, but not in the snow. Instead it's done with running shoes and shorts, and with handguns. Short courses of fire, speed of movement is essential, so is accuracy, and the fastest time with the best hits wins. Top competitors run, I don't. But I have accuracy up my sleeve, from my years of experience, to make up for their speed. That's USPSA Action Pistol, but in that I shoot a 9mm PCC SBR (pistol caliber carbine short barreled rifle) and not a pistol. Then there's Steel Challenge that is pure speed shooting (accuracy does count) with virtually no movement. The younger shooters speed of movement is no advantage in that and it shows. I do pretty good in that since all it requires (mostly) is swiveling at the hips.
