Since no one else has brought it up...
There is always the military option. I'm not going to preach or get into any details, there are other threads you can read, or you can ask me and I'll tell you more. I was a business/engineering major in college, and then went off to fly for the USAF for 9 years. I loved it and wouldn't trade it for anything.
But that was my experience and you need to figure out what you want.
As far as what everyone else is saying, the one thing I ABSOLUTLY agree with is to major in something that you're really interested in. You'll enjoy college a whole lot more AND you'll get better grades doing it!
Good luck!
