You can do quite a lot with an English Literature degree. A lot of students who take English Literature as a degree are often people who want to be writers themselves but that doesn’t mean that it stops you from getting into other careers. But I think if your going to take a degree in English Lit then you should take it because you enjoy it and its something you want to use because otherwise it might turn out to be pointless. it’s a highly respected subject but obviously its going to limit you to some careers such as law and medicine because they require you to train in those fields but the majority of students who take English Lit have some idea to what careers they want. You mentioned that you take medicine to be a doctor but that’s quite a specific field where English Lit tends to be a little more broader with what you can get into.
You could be a journalist, teacher, lecturer, publisher, reporter, researcher and careers within the media and IT. I’m sure there’s many other careers you can get into but there just a few to name.
