I didn't really know what I wanted to be, but in hindsight it's mostly because I didn't really know any options. In a small town in the 90s it was finish school, then go work in a shop (girls) or a factory (boys). That was the assumption and basically the whole career "advice" setup at my school.
So it kinda makes sense that nobody there seemed to have any ambitions.
Thankfully, I eventually found out that you're allowed to work with computers. Maybe someone would've mentioned that to me earlier if I'd been male but again, 90s. I taught myself web development, made a living off that for a while, eventually had enough and pivoted into being a small-time craft YouTuber!
