DS1 wanted to be a carpenter. Then (mercifully, says she, thinking of the usefulness of a full complement of digits) an English teacher. For which, it appeared, he chose a very odd collection of A levels. Until it turned out that he was actually intending to apply to study Biochemistry, for which they were just the thing. A few years down the line and he's doing a PhD in Fossils, with the intention of becoming an academic fossil person. I think. From a very early age, he could tell anyone who didn't move away fast enough all they'd never really wanted to know about dinosaurs, so it's probably a reasonable direction to aim to take.
DD was going to study Law. Then actually did a degree in IR with French, then spent a year in a couple of jobs neither of which was related to either. Now doing a masters (LLM, but 'International' and 'Global' and not, as far as I know, actually intending to be 'a lawyer'). Then, who knows.
DS2 graduated this year and eventually wants to work in the realm of museums / galleries/ libraries, for which his degree suits him, but in the meantime is just earning money. Not a huge salary, and it was the first job that he was offered. And that probably because he turned up on time and had had a shower beforehand, although tbf, he is also generally polite and speaks nicely (it involves a lot of telephone stuff - and no, not cold calling, although he's already had a couple of people who had obviously forgotten that they'd asked for someone to ring them and accused him of such
). Early days yet; as for all of them, I just want him to be happy. Well, and doing something socially useful, for preference (DD's last job possibly preciously sailed close to the line there, but apparently the company is one which acts legally, which is comforting to know, since they apparently thought that she was very good at it).
