Daily reading can have so many different benefits, one of them being that you learn new words, which means expanding your vocabulary. If you have a bigger vocabulary you can read even bigger books because you know more words. Another benefit is you have a bigger imagination, I think this because the more books you read you go on more adventures and learn about new things.
