I basically just learned it on the job, from examining some existing queries that we used and then messing around with it, and a few tutorials on the side.
I'm kind of in between the business and tech. I make sure some of our internal software is running correctly and I run SQL queries and stuff to look for problems in our data. I can help create stories to pass to IT for them to develop fixes for issues or for new functionality in our software.
Graduated around 2008 as the economy was crashing, and struggled to find anything. Eventually got hired at a call center for a large company (about a year after I had applied for it). After a few years of that I was able to transfer into a different department where I didn't have to deal with customers directly, then kept getting promoted to different positions until I found one I was really comfortable in.
I've found that as I got older, my taste in games has narrowed significantly. I used to be able to play pretty much anything, or especially any popular or critically acclaimed games. But these days I just don't give a shit about most of what's out there. I do have certain genres and developers that interest me though, so I know there are occasionally going to be some new games that I really like. And every now and then I might get surprised by something too.
If you want to get non-techy users, then there is absolutely no need to even use the word fediverse or to try to explain what any of this means. If you want to help a friend get onboard, just send them a link to sign up on the same server that you use, or a nice general purpose server. That's it. They sign up, they use it, and THEN they can start to learn about fediverse shit if they care to.
I played the VB a ton when I was a kid. I guess I was just a dumb kid but it always felt fine to me, I never felt any eye strain or anything. Maybe I just have super eyes.
