Probably best to limit it to ones you had a choice of getting into, rather than "yeh Formula 1 driver lol"
I sometimes wish I'd studied engineering at university for a bit more flexibility in job choices, but then I remember I'm not brilliant with numbers so that probably wouldn't have gone well.
It might have been nice to be a bench scientist, but I kind of had that option and it's a pretty awful career choice for lots of reasons so I'm fine with that decision.
My gf wishes she was a dentist. A dentist! Jfc.
