Yes - my job is now a graduate profession (twasn't always), and the subject is important too.
And actually, for teaching, i don't think that's just hoop jumping. I do use the stuff I learnt on my degree a lot of the time, and more to the point - the stuff i did on my degree was the foundation for the areas i later discovered on my own, and which also inform my teaching.
tis odd, really - i'm completely the sort of person who would end up doing something unrelated... but on the other hand, i've always been pretty much in love with all things dramatic and theatrical - so I guess it also makes sense that i've ended up in the same field i was interested in as a teenager.
