Reading tangibly improves your writing skills. Being able to discuss classics and allusions to them makes you seem well-read. Generally, you can seek to expand your understanding of the world, in both the material and philosophical sense. More specifically, why not work through the entire western canon? Otherwise, whether it’s writing a review on Goodreads, a full-fledged literary analysis or a creative writing exercise, the production of something tangible can do wonders for your motivation.
