Really pisses me off when people ridicule others who say they want to earn 30k out of uni. It's not unreasonable at all. It's difficult, and you'll have to get through competitive procedure, but it obviously can be done. Almost all accountants, strategy consultants and middle/back office bank jobs pay around £30-35k. The front office bank jobs, as well as management consulting pay £45k+ out of uni. It's not only in finance that a lot of money can be earned straight out of uni. Petroleum Engineering, Pharmaceuticals (though usually need a PhD, not always), technology/r&d, software engineering etc. all earn over £30k a year starting.
Anyway, I don't really know what I want to do for a job, I find the idea of developing software interesting but I haven't started to practice programming yet so I don't know if I'd really enjoy that - definitely a possibility.
I'm gonna aim to do something I enjoy, and if something I enjoy earns megabucks, great (and if you want a figure, probably £30-35k would be nice but if it isn't possible with the line of work I want to go into then fine)!
