You know how some people will say to writers, "Why don't you just write a romance novel that sells a bunch of copies and then you'll have the money to do the kind of writing you want to do"? I always say that I don't have the skills or knowledge to do that. It would be just as hard for me to do that kind of writing as it would be to learn how to do any number of productive careers that I can't manage to make myself do.
