Just because one studies a subject does not mean someone "becomes" that job right away; jobs/occupations/callings, etc. take experience as well as knowledge and skills. Because you are a carpenter who can frame a house does not mean you can build a set of stairs, necessarily. School is mostly theory rather than "use" and what we learn can be used in a multitude of ways and it is up to us to apply the theory to the area of use we are most interested in and come up with our job/career.

I liken it to working for a large box store, say Walmart. Studying "Walmart" and its history and what it does and how it does it, getting a Wharton MBA degree in Walmart does not mean one could instantly take over as head cashier or even as CFO? Managing distribution because one has a business degree in transportation doesn't happen right away, one has to work 10+ years and work one's way up, no matter the field.

I think you should look for ways to get some practical experience, to make sure work in the field you are studying is what you want. If you have a degree in history, for example, you need to work for the Government or at a museum or a library/archive, etc. Just knowing "about" the Battle of Gettysburg and having a doctorate in history does not automatically get you a job as a Park Ranger there, you would have to have decided to pursue a job as a park ranger long before that and factored in that career path: http://www.nps.gov/wrst/parkmgmt/upl...omeARanger.pdf

What job/occupation do you want specifically? I would look that up and see how you could get experience to work up its ladder. Deciding to be a writer and getting a Doctorate in "Writing"/Journalism, one still has to actually write something. Engineers have to actually build good bridges or airplanes before they are sought as good engineers, etc.
