I would be surprised if the majority of people actually chose their career, rather than ended up doing that due to the vagaries of fate, but that might just be my perception.
Good point Simmo. Most people take what's available when they need it.
Apart from which, how many of us know so early in life a) what we are good at and b) what we
really want to do?
A major pitfall for those of my age and older was that careers for girls were so
very limited. If you were not too bright you could work in a factory or shop and if you were bright you could be a secretary. (My Careers tutor hated me because I was kicking out then and she used to have to look up all sorts of societies and addresses for me because I refused to be any of them!)
Nine times out of ten by the time many of us have realised what we really want to do, we are firmly ensconced in a rut.
Changing course to a preferred career can be very difficult if your c.v. reads another way, and taking time out to get the relevant training/experience can cost time and money, not to mention the strain it can put on a family.
I got chucked out of home at 17 with nowhere to live and no job either, so that was all the dreams and big ideas down the pan immediately. Took the first thing that presented and, unfortunately, it took me years to shake off the image that my c.v. presented when I tried to change direction.
I'm still not doing what I would like, but have managed to get a c.v. that is more than acceptable to the kind of work I am doing now (qualified for a much higher grade, but I like the people where I am).
I do get a fair amount of job satisfaction from helping out patients who have got messed about by the system and am currently surprising myself by turning out to be rather a good organiser and communicator.
Not bad for a seemingly scatty redhead - but I always wanted to be either a herbalist or a vet.
