Qualifications

Study what you love. Most people do not end up in their field of study unless it's law, medicine or accounting. As a former Art History major I can tell you I loved the education, but knew I could not make a living at it. In the 80's I helped found a company that designed and installed computer networks for small business' - a job that did not even exist when I was in college. Now I'm a landscaper. Go to a good school, enjoy the journey and don't worry about the details.

My profile gives a pretty good overview of my education. If there is anything I can do to help, just ask.

to decide on a major should be dependent on what you plan on doing. If you just want to go to college just to go, that would be a bad idea. I think that since you are in this interest you have made up your mind. Look for proffesions where you could use your history degree.
Oh, I have a BA in history and am a highschool history teacher
