Rather than leaving tech to turn to writing, perhaps you could find opportunities in your current job to write. Even something as seemingly benign as documentation is something! (And in truth, we need more good writers and editors working on documentation. It’s not sexy but it impacts so many people and often the difference between good and bad documentation is the ability of the writer/editor.)
Great advice! I'd take it a step further: we need more good writers working on the documentation that's needed before the code is written. Call it Business Requirements, Functional Specs, Technical Specs, Stories, or whatever, almost everyone sucks at it and almost every project suffers by the lack of it. No one reads documentation written after the fact (it's not sexy), but projects are saved and careers are made by those who can write anything that helps the people actually building the software. I may be a little weird, but I think that's very sexy.
