I kind of have two things that I do (for a living).
On the one hand I am a motor insurance claims advisor. It is about as exciting as it gets. If I take anything from that and bring it here it is the ability to calmly and succinctly teach people complex financial regulations whilst their car is upside down and on fire (keeping a cool head in a flamey situation).
At the moment, I am in a secondment - as a software tester - with some interesting prospects. That is much more in alignment with the career I was going for. That requires trying to communicate how (and sometimes why) something doesn't work to a chain of people I'll probably never meet. Which I suppose is another skill useful to debate forums.
When I'm not doing all that I work with a charity which strives to preserve traditional (British predominantly) folk music.
