Nabokov is partially famous for his discussion of what makes a good reader, and by correlation, what makes a good writer.
Nabokov mentions in his long reasoning that one important aspect of a reader/writer, is the ability to separate the reader’s world from the world the writer creates. But I disagree with this. The best thing about stories is the ability to connect things from your own world to the world the writer creates, whether its understanding the situation a character might be in, to imagining a location to something you’ve seen in your past or everyday life.
That is what makes books so much more imaginative and mentally stimulating than movies, when you read a book every person who reads it has a different image in their mind about a location, or even a character. Not to mention if we followed Nabokov’s example of not inserting ourselves into the story we might not feel the same nervousness, satisfaction or fear that the story presents.
