You know, I was a materials engineering major out of college, and I had a really hard time deciding as well. My current attitude is, I guess I count myself lucky that there wasn't whole lot of development in the biomaterials industry, or else I'd probably have a job somewhere else instead of here!
When I first graduated, was looking for jobs, I was only focused on jobs related to my major. I didn't think that anything else would be rewarding as a career. Then my buddy, who just got back from OCS (Sub Nuke!) asked me, and I'll never forget: "Maybe not related to your major, but is there anything else you'd like to do instead? Maybe flying?" And that's what got me. After that, I did a lot of looking for reasons not to, but the more I looked the less I could find.
And now one of the things I count myself grateful for is not working in an insipid office job somewhere, even if it's something relatively interesting like biomaterials. I just winged, and applying to this was one of the best decisions I ever made. Ever made.
So take that for what it's worth, I don't really know what your passions are, but there's my .03c biased opinion.

Oh yeah and a lot of NFO's get out and go work at Boeing or Lockheed anyway, so there you go.
