Like all the greats, Chimamanda Ngozi Adichie is an unrepentant bookworm. As she told Stylist:
Read, read, read. I’m not sure that one can be a good writer without being a good reader. If you’re going to build a desk it’s very good to see what other carpenters have done.
It seems obvious, but you would be surprised how many writers forget to take the time to see what great new books are out there. It’s not just good research, it’s also helpful to scope out the competition. See what you’re up against and that will push you to do better.
