For a different idea, if you're interested in the human side of marketing, I might suggest looking a digital marketing. To be a successful digital marketer, you have to know your customer and this starts to get in to human behaviors and customers experiences. While all marketing is connected to business, there is an interesting side to this type of marketing and communications that includes a very human element, and it often includes social media channels. This type of career would absolutely work into your desire to work with words. It might be worth looking at this type of career, just as an alternative.
