Let's be practical here. She has no business turning her back on the very thing that has been her bread and butter all these years. She has no right leaving a business career for something so ridiculous. It is totally irrational. You've hit the nail on the proverbial head.
Writing is a business.
She is definitely going to need all those organizational skills to gather her thoughts and get her queries written. She is going to need her analytical abilities and marketing skills to help target her work to the appropriate publication. She will be utilizing her researching and interviewing techniques in writing those wonderfully detailed articles. Well, I suppose those are valid points. In theory, it does make perfect sense that business skills are a necessity if one is to succeed in the writing field.
