Should I get a degree?

I'm 24 and I've already graduated college with a Finance and Analytics degree. I work in banking and I have a pretty stable career fortunately - but I have such a love and passion for literary analysis. I love reading Dostoevsky and Sartre, and I have had a great aptitude in understanding the deeper themes and narratives, and I'm continuing to explore other classic novelists. I've made videos online analyzing different books and it's been so fulfilling in how it's inspired strangers seeing my videos to read!

I want to expand upon my aptitude and get an academic understanding of key concepts, ideas, and frameworks. I'm also an aspiring writer.

First, is it worth getting a degree at all? Again, I don't really plan on changing careers; I'm moreso doing it because I'm passionate about it. And who knows, I dream of being a literature teacher or professor in the future one day, if I can get the credibility.

If I should get a degree - any programs that would be suitable for me?
