I just want to point out that Sel's word count per update is not normal even among professional writers. He may well have been a professional at some point, but the average novel is 75,000 words, and to say that this amount of words is normal for a professional every month is not very realistic. Some authors are truly prolific, and Sel is one of them, but being a professional does not mean that you can just write thousands of words every day all day with no issue. For all of his shortcomings, he is consistently good at writing decent prose at an astonishing rate.
