To be a good novelist, you need to keep your sense of curiosity alive. You need to be the kind of person who wants to know things: about people, about events, about objects. What made you want to become a pilot? Do you get on with your sister? What is that police car doing there? Who lives in that tiny/big/smelly house? Who dropped that hand-written note in the park, and what does it say? Good fiction writers are nosey. I think “write what you know” is the single worst piece of writing advice. Instead, write what you’re really interested in. Write what is going to keep you awake at night; write what you don’t understand; write to figure something out. Good novels are journeys into the unknown, for their authors as well as their readers.
