As almost everyone has stated, if you're not sure what exactly you want to do, you're better off saving yourself thousands of dollars and going to a JUCO and earning credits that transfer to a larger school. If you end up going to larger school, say UNL right out of high school, you can always pick up a class or two during your summers off to save a little money, that's what I did. One thing I will add is that I don't think private schools are worth it, value wise. Unless you go for religious reasons or you receive scholarships that reduce the cost to state school level, JUCO and/or state schools are a better value.
The 'Great Recession' has really opened my eyes to analyzing education and the job market after graduation. To me, it has made one thing abundantly clear...now more than ever, you must look at the value that a specific school/degree will provide for you later in life. In my experience, the bigger the school, the better in some sense. I don't mean to come off as some Texas sized jerk-off, I'm not a native, I just work here. What I mean by that is, on a resume, a well-known state school (example UNL, Iowa, Indiana) is more recognizable than a small school (think Truman State in Missouri or Hastings College). Also, more companies and recruiters attend these schools' job fairs, sponsor academics, serve on various Boards etc. I'm not degrading smaller schools by any means, but when thinking about what your future college can facilitate in terms of career prospects.
Also, major in something that the job market demands. Develop a set of unique skills that you can offer employers...busines (not general, something specific like finance or accounting), science and engineering, hell, Golf Course Management works. This will greatly help you in the future job market. I know several people who majored in Sociology, Psychology, English etc and can't find decent jobs. That's because they didn't learn a unique skillset. Sure, those are interesting subjects (as electives), but what value can you create with an English major?
There are exceptions of course, but play the odds on this one, a lot of time and money is at stake. I'm sure I came off as a prick with no emotion, but you really have to look at the cost/benefit...I'm an accountant.
