What an illuminating post!Since i was literally old enough to walk, my fascination has been with lighting. Specifically entertainment lighting. I'd play with all the dimmer switches in the house seeing how the lights operated and the looks that could be created, and when my dad would take me to a concert or to something like Sesame Street Live, I'd spend the whole time looking up at the lights. Dad would get pissed that he spent all this money when I didn't watch the show. Spent my high school years in the theater, designing and running lights for the shows. I was led into engineering in college, but quickly dropped out and switched my major to theater production.
And what do I do now in my mid 40s? I play with lights, and program lights. Now, I'm not in my dream job, but it's dream-adjacent. My dream would be to work designing systems and programming in musical theater for the rest of my life, but there's just not much money there unless you make it way up the ladder and work non stop, and you pretty much have to live in NYC. Instead, I worked in corporate events and museum exhibition lighting for years. And now, I work in the film and television industry as a lighting programmer and data tech. It pays quite well; provides a substantial rental income for equipment I own; provides full heath insurance, retirement, and other benefits; and I get multiple free catered meals every day in addition to never-ending snacks and drinks. Pretty hard to not love it.
So, I'm childhood-dream adjacent.
But glad you are almost doing your dream job.
