When I was very young, I wanted to be a trapeze artist or a pilot - I was good at gymnastics at school and lived near an aerodrome that hosted an annual air show and there were often small aeroplanes, even occasional biplanes flying over, so I figure that's where those came from.
Had a disagreement with an RAF careers officer when I was about 13-years-old when our high school took us to a careers fair; I told him I wanted to be a pilot, he said I couldn't, because I was a girl. (At that time, they didn't allow women to be pilots, although tbh, I'm probably too short anyway.)
I was good at science and maths at school and did end up studying electrical engineering at uni for two years, well, a foundation year then first year, but flunked my end of year exams because my father assaulted me about six weeks before the exams.
I figure in a parallel universe I'm an electrical engineer.
Drifted into office work, temping, to pay the bills and keep a roof over my head. Ended up doing legal secretarial work, because it was higher skilled and paid than regular secretarial work, worked my way up from temp to float to permanent legal secretary and ended up working as PA to a partner who specialised in M&As at one of the country's top 10 law firms (not a magic circle firm). Started a part-time law degree while working full-time. Was asked to cover maternity leave for the PA to the head of a different department. As an incentive, the HR woman offered me funding to do ILEX (Institute of Legal Executive) exams, I said 'Why would I do ILEX exams when I'm already doing a law degree? Will you fund the rest of that instead?' It went all the way up to the managing partner, and fortuitously the recently promoted managing partner of the whole firm was also a specialist in M&As who'd led teams that my boss worked on, so he knew me. It was unprecedented, to fund a legal PA through a law degree and then training contract, but he agreed, they would not only fund the rest of my law degree, but would offer me a paralegal job after the maternity cover, and in due course a training contract as a trainee solicitor.
A sticking point was salary, because I knew that paralegals earned less than I did on a full-time legal PA salary plus overtime, which was relatively substantial, as I often worked 10 or 12 hour days, the longest shift I did was a completion meeting that tied in with a stock exchange deadline, around 32 hours with only a half hour break. Paralegals and other 'fee earners' generally didn't earn overtime pay, just their set salary, so it would have meant taking a pay cut. The HR woman in our local office agreed an increased salary with me. But then she went on honeymoon for three weeks. And so a more senior HR bod from a different office stepped in and pulled back on the salary. So I threw a bit of a hissy fit (not a real one, just in my head) and applied for another job and got it.
I've occasionally kicked myself for giving up that opportunity. If I'd stuck with it, I'd have have been a corporate lawyer earning shitloads by now. My workaholic boss ended up the head of office for a different law firm and I'd had a really good grounding in M&As from them.
Again, in a parallel universe I'm a rich corporate lawyer.
The job offer I took up was training to be a court reporter/legal editor. I worked on a really high profile in the news headlines court case. Unfortunately, it turned out I couldn't transfer my law degree studies to a uni in London, because the course structure was different.
Then went travelling and switched career again, did a bit of journalism, then got a relatively well-paid job for a while. In an ideal world, I would've liked to have worked my way up to reporter, worked in the field. But embarrassing admission I have a bit of a weak bladder so working out and about away from nearby toilet facilities wasn't really an option for me.
Instead, since then, over the past couple of decades I've had a couple of mental health breakdowns due to housing problems, antisocial behaviour and harassment from neighbours and also bullying and harassment from housing staff.
So, like Gromit mentioned about alternate realities, all of the above were possible forks in the road.
While resigning myself to an engineering career and then legal career not happening, I sort of resigned myself to not being well-off, not least because I'd become a bit more anti-capitalist-y and activist-y, so was telling myself I didn't want to sell my soul for a corporate job.
In hindsight, I wish I could go back in time and tell younger me that it's easier/better to opt of out of the capitalist system when you've already made some money out of it and have a comfortable financial cushion, because being poor in middle age and facing a retirement living in poverty ain't great.
As for other pipedream careers, something involving living and working in France permanently (rather than my temporary stints) would've been good.
