There probably are more at https://bloom-site.com/about/ ”literary site devoted to highlighting, profiling, reviewing, and interviewing authors whose first major work was published when they were age 40 or older.”
Also, it depends what kind of writer you want to become - some options are easier than others. For example, would you classify a journalist as a writer? Is technical writing "writing"?
Barry Eisler is a good example of a writer who broke into writing gradually. A former lawyer, it took him 7 years to get his first book published. He wrote in lunch breaks, on flights, after the kids went to bed. He had to re-write that first book at least twice based on feedback from agents/publishers.
Ted Chiang is an example of a technical writer who changed into science fiction writing.
I changed from teaching into technical writing.
How you will change into writing (which I assume is what you want) will depend on your starting point and how far down the road to becoming a writer you already are.
p.s. Have a read of "Big Magic" by Elizabeth Gilbert - I believe there's much of value in her suggested approach.
Fiction about 2 devs that sell coke to fund their redundant start up
The initial book just poured out of me. I had an outline, I knew exactly what I wanted to say and I just wrote the content. In that way it was like tackling a college paper or trello board, but instead, a few hundred pages of text.
Like I've said.. no other ideas have really coalesced into something outlineable and easy-to-market.. I have one manuscript that's 80 pages and sucks, another at 40+, etc etc. Reminds me of the hobbyist programmer population here with tons of unfinished projects.
I really had something to say and felt entitled to say it.

I'm in marketing, and before was focused quite a bit on social media content which was just quick little snippets accompanied with a photo. Now I write mainly long form content for blogs.

If you like writing, you can incorporate it into many careers, without having to quit your job and be a starving artist.
