I too fancied being a vet until I realised the sciences were not my best subjects at school. I "flirted" with farming too but, short of marrying a farmer, I knew it was unlikely I'd make much of a career of it.
Strange as it may seem, I liked the idea of the Civil Service from the age of 15 and, for my sins, that's where I ended up. I always had a secret fantasy, though, that one evening I would be at a concert, dance or whatever and the singer (Big Band or Jazz, to my liking) would collapse on stage. Up I would rush, blushing modestly, and say, "Perhaps I can help you out", whereupon I would be "discovered". It never happened so I had to make do with Folk and Jazz Clubs and Whitby Operatic Society.
Incidentally, my
other career was wife/mum. I think I was quite good at that.
