I haven't even started yet, starting this September, and I'm really hoping I get some kind of divine inspiration in the next 3/4 years for what I'm going to do after uni. I can see myself doing a Masters possibly, but still, after that. And from what I know now, I'd probably do Masters part time like a mate of mine is doing so I could work and actually afford it if I chose to do it.
The other main worry though is making lots of friends and having just that general social feel from having your peers around you, in class and in halls (particularly because I only had a couple real friends through school and bunked most days)..... and then losing loads of friends because of distance/general flakeyness of people/having to work all the time etc....
Iunno though, there's loads of things I'm looking forward to about life after uni, I just need the stability of a job for them of course and it would be nice if I was doing well socially too... will just have to see how it goes...
