When I was a kid, I did pest control because Mom managed the office there. It's obvious that you're saving people's homes and trees.
When I was older, I wrote software that kept power plans safe by making sure that the fire protection equipment was inspected.
Then I ran an Internet Service, back in the days of dial up. I helped hundreds of people get on the internet back in the 1990s. I wrote the software the used to install WinSock.
At the same time with the internet, I also repaired industrial control electronics, which were used by industry in mighty rolling mills that stretched steel like taffy.
After that, I was the computer guy "Manager of IT" at a company that did marketing campaigns for large corporations at trade shows, like CES, etc. They would come to us way too late, and we would scramble like mad to make sure they were able to deliver their message to the world. My little part was to make sure that about 50 people could use their computers and the servers I managed, to get everything done, regardless of where they were in the world.
Then I worked in a job shop, where we made gears. If you have a Marvel 8" bandsaw made between 2015 and 2019, I ran the Gleason Bevel gear cutter that cut the teeth on the lower band wheel and the pinion that drives it. I also learned a boat load about the process of production, and the culture.
I've never worked for government, all of those jobs helped other people, directly, or indirectly. Made them safer, happier, more well informed, in some fashion.
