Writing book reviews for yourself can be an excellent way to discover who you are as a reader. It can help you figure out your favourite genre, who your favourite authors are and what you like and dislike while reading. And if your TBR (to be read) list is longer than the books themselves, like mine is, writing book reviews can help you decide which book you'd like to read. A section you could add to your reviews is 'Favourite Quotes', a sweet way to commemorate your favourite books.
