I am a bookworm. My bedside table is never without a book and I would choose a chapter over an episode of series any day. A book exposes you to new vocabulary, sentence structures, and all aspects of grammar, however, a great book invites you to explore new aspects of yourself and create new patterns of thinking.
Recently I have started reading 'Sapiens: A Brief History of Humankind' by Yuval Noah Harari, and would highly recommend it. What are you reading? Let me know in the comments and I will create a booklist for you to share with your students.
