I think that you’re making an incredibly brave choice. It isn’t easy to walk away from something (like a nursing degree) after you have invested so much time, energy, and money into it.
You mention wanting to pursue a career in Art History and/or English — does this mean you will be switching majors to work toward a dual degree? For career purposes, I would recommend getting a degree in either or both Art History and English (if you aren’t already), but that may not be a feasible option for you. I don’t know much about opportunities for English majors (maybe this website will help give you some ideas), but I do know that there are many career options available for art history majors that don’t just fall into the traditional categories of teaching and museum work (e.g., see here and here). Take a look at those websites and see if anything jumps out at you. Are there any similar career options listed between the English and art history sites? If you found something that looks interesting, what would you need to reach that career goal — grad school? If so, in which major? What kind of prior experience may be expected of you, and can that be obtained while you’re pursuing education in art history and/or English (i.e., internships)? One thing you might want to do is look up actual job descriptions for the types of jobs listed on the aforementioned websites and see what the “real-world” requirements are. This will give you a good idea of what to work toward and how long it will take you to get to a hirable point (e.g., if you need 2 years experience in X type of work before obtaining your desired job, it will take at least 2 years…) The great thing about being interested in English and art history for a career is that you will have lots of options to chose from. You might even want to pick a “Top 3” for careers in each category and narrow from there which ones would be the most viable for you.
You’re right that finding a job in art history isn’t easy. (I can’t speak to English, but I imagine the situation is similar.) Art history is an extremely competitive field; you have to be competitive, and in order to be competitive, you have to have a fairly good idea of what it is you want, what your end goal is, so that you can take steps toward making yourself the best candidate for whatever your dream job is. One thing to consider in making yourself competitive is money: if you do think you need a graduate degree to pursue the type of career you want, then make sure you apply to programs that offer some sort of funding to lessen the financial burden. Art history is not a lucrative field — at least not right out the door. That’s one reason why it’s important to have a clear picture of your career aspirations in mind; hopefully, knowing (even generally) what direction you want to go professionally will keep you from falling into educational & financial limbo.
I don’t mean at all to discourage you; only to provide you with honest information so you can carefully assess your options. Again, I think you’re making a brave choice, and I think that any risk present will be worth it because you’re following your passions.
Your work is going to fill a large part of your life, and the only way to be truly satisfied is to do what you believe is great work. And the only way to do great work is to love what you do. - Steve Jobs
You will be & feel rewarded for following your passions. Maybe not right away, but it will happen.
if you work really hard and you’re kind, amazing things will happen. - Conan O’Brien
I wish you all the best, and please keep me posted on your adventures!
I hope this helps!
