I wanted to be a vet, then realized I'd never pass the more chemistry - based parts of the exam.
Then wanted to be a translator because I'm good at languages, and realized it was mostly gonna be excruciatingly boring technical shit I'd be asked to translate rather than wonderful works of literature.
Wanted to be a jockey next - can ride, love horses, love going fast on things, am ultra - competitive, got the naturally right figure. My dream job that I was actually cut out for. Only they take them early at racing school, like 15 - 16. At that age my parents insisted I pursue an academic career because I was 'gifted' and becoming a plain old jockey would be squandering my talents. And by age 17 I was on the junk and stayed that way for 5 and a half years, didn't manage to finish uni anyways, and they don't accept you after 18.
Next ambition, be an archaeologist (always been fascinated by history and I want to do something physical, so I'd like to be a field archaeologist, ie the ones that do the actual excavations). This one's still standing although fuck knows when and how I'll be able to afford to take the necessary courses.
... In the meantime I'm a freelance photographer and researcher.
In addition, in my childhood I had thoughts about the career of a lawyer, because I really liked watching films about lawyers who professionally and eloquently defend innocent people. On the site
