I may have several fixed mindsets due to a pesky Dissociative Disorder. As they live to tolerate each other under the rubric of this - my body or have been integrated in me my mindset changes depending on which alternate personality is speaking.

This may account for lengthy or run-on sentences. I think my writing as been improving. Although I don't edit responses much. I have worked to improve and change.

I have been writing fiction and non-fiction on and off for 61 years. Maybe that says something about not remaining fixed.
