That always depends on what "studying" means to an individual. I wouldn't say I'm studying it, per se, but I have been working on writing for over a decade and have held hour-long conversations with other people passionate about the craft, discussing and hypothesizing, reflecting on why you are writing things the way you do, and mirroring stories you read, to see what possible intent could have been going into that.
Whether that can be considered studying or not, I do it because I find it fascinating. Sure, I'm selling my books as well, because there's a certain range to books you are selling. They end up on lists and become "official", but all that depends on how you see it. In general, I just love stories, and I love telling stories. Bottom line is, that's all I care about when it comes to writing, so I try to refine the way I'm telling my stories, because that's why I'm doing it in the first place - to entertain someone, even for a minute; to make them wonder.
Compared to that, a little bit of work is nothing.
