Answer:
Changes in thinking lead to changes in writing.
Explanation: Changes in thinking can lead to a different point of view. Wheher if it's how you play piano to how you make your bed. It affects how you do things. So in english, if you change your thinking to a different prosepective, then you can change your writing to a different perspective.
Let's say your favorite book was in third-person point of view. The theme was about jealousy. The book was about a girl having all she wants and the other girl has little money, and is jealous of the previous girl. If we change this to first-person point of view, the theme can change. Let's say the first girl is writing the story. She would probably be bragging about what she has.
This is how changes in thinking can lead to changes in writing.
Hope it helps :)
