Henry,
Let me join the chorus with comments/opinions about the purpose of college. Before presenting my position, let met outwardly state that you seem to be coming from a position of relative privilege to adopt the attitude that you have. (I feel comfortable in the assertion as I have a privileged perspective in my educational background). Don't take that privileged position for granted, as it may also change
College has several overlapping (and slightly contradictory) positions.
1. Above all, college should as a foundation for one's life education. Learning how to think critically and argue rigorously (by proof), to analyze and synthesize information, and to quantify are hallmarks of a sound education. College should also serve as an exposure to novel ideas, people with diverse backgrounds who can augment your own, and the best of many cultural expressions and traditions. A college education is an exercise in drawing forth one's ability to reason and think methodically. In other words, it's not about the facts that you come across but rather how you learn to process those facts and act intelligently with them.
2. Credentialing -- Yes, unless one plans to exist on a trust fund for the rest of one's life, most of us need to use parts of college as a form of credentialing. You certify to the world that you have rigorously studied a certain area of knowledge. Admittedly, many people will not work in the field which they studied in college, but it is important to take one's training from the academic experience and move forward.
---> NJQT has 3.5 degrees from art history to nearly plastics engineering. I have an undergrad degree in biochemistry and am finishing a masters in computer science. As we grow older/up, we make life changes or course corrections, which often involves a re-education or re-tooling to meet new challenges.
3. In college, learn the theories well, but also focus on the applications. Earning $$ is ultimately in the application of one's knowledge. One very bad conceit of academia, in general, is the elitist tendency to focus only on the theory when it's the practice of a discipline that society also needs. In the sciences, it's well understood that one would never just study "theories in science" without having some experimentation/practical application to complement the studies. In the social sciences and humanities, the value of the "practice" if often left as an aside, even though the practice may be the most valuable aspect of one's education in the end!
---> Henry, art history/the theory of aesthetics/visual studies, is quite an interesting pursuit. It is a privilege to devote a certain period of time to these studies. Admittedly, the content is highly rooted in subjectivities and theories of interpretation. You, however, still probably have to figure out a way how to transform what you know into something that can earn a living. ...
The easy/straight-forward way is to go seek employment at a museum where one's academic background in art history has the most relevance. If you decide to spend years in a museum environment, you will ultimately have to figure out how to become a curator or director, which involves further studies in business, finance, and management as applied to the art world.
IF, however, you have more of a "production" oriented mindset and know digital arts programs - FLASH, In Design, digital video experience, you can use the elements of your academic training and apply them to the digital domain. You will then have to work to rise in positions that are multi-media intensive, but you will need years to develop portfolio pieces and become established. You may end up returning to school for an MFA if so...I merely am presenting practical avenues of growth and education for your future.
IF, you feel that art history has no appeal to you in any application, you may find yourself seeking (re) education to ultimately do what you desire. Never forget that education is a life-long pursuit and do think of many people in their 30s and 40s who seek advanced education or re-education into an entirely new field.. (Nursing is both popular and lucrative at the moment: people are goingback in droves to take science courses to meet the critical shortage in nursing care. These are the same people who thought they would not hack it in science courses earlier on as high school students or traditional college kids).
4. College is a place to grow up.
The 19th century notion of sequestering adolescents from the rest of society to "grow up" is a bit bewildering. It's like assembling people who have little or no clue about many aspects of life and telling them "to figure life out" on their own. College does afford time for some personal experimentation and growth and gaining a sense of independence and personal responsibility. Use the social freedoms of college wisely for that purpose.
