The future.

I often get reminded I have to plan my future (which I haven't done) and today we had a talk on ucas applications.
Of course it was all about uni and how to decide what degree to take and which uni to choose.
WHAT IF I DON'T WANT TO GO TO UNI.
They aren't even giving us the choice to do anything else. I told our head of year that I'm not planning on uni but he doesn't seem to but able to contemplate that idea. I just want some support to know what my choices are OTHER than university's.
