Last time I dropped in a poll about why we write (or do our other art). So let’s get to those results!
Top response: “I enjoy telling stories.”
Followed closely by: “It’s my identity.”
Trailing responses: “It’s self-care” and “I have something to say.”
People can get focused on different measures of success, like sales figures and review ratings. It’s important to remember that writing (and other arts) are pleasurable and relaxing. Life is full of stress, so relaxation is something we all need, assuming we can cut through the stress and have fun with it.
Have you read one of my books? Then it would be great for you to leave a review! Meanwhile, if you’d like to learn more about me and my work, check out my website, Facebook, Instagram and/or Twitter.

As I posted under your poll, I’m sorry I missed it!
But I’m sure I would have checked all four of the choices you listed (and maybe done an Other).
Interesting responses. As it turns out, I checked all four. If I had been able to rank my choices on a personal level, I probably would have ranked them in an order close to what you report for the results.
It’s neat that none of the responses are, “To make money.”
I deliberately left money out of it.
