Hi @crooked-daybreak-310 reading of any kind is very useful. Whether you are reading fiction, non fiction, magazines, comics or graphic novels. There is research to show that just the act of reading is extremely useful.
As everyone has commented, fiction is a great way to build language and also creativity, get new ideas or just change perspective.
I read both but have recently been more biased towards non fiction- but some books are harder to finish than others. Fiction I allow myself on holidays only as when I start fiction, I generally canβt put it down until I finish it - causing to be physically present but mentally absent π
