A messy book is a well-read book, a sign of knowledge acquired. It's easy to spot a book that has been loved and used frequently. The pages are bent and creased, the spine is worn, and notes are scribbled in the margins. These imperfections are not a sign of neglect or carelessness, but rather an evidence of a book that has been fully engaged with and understood. A book that is kept in pristine condition may look nice on a shelf, but it is also a sign that it has not been read as much, or not as deeply. A well-read book is an indication of a curious and active mind, always seeking to learn and grow. So, don't be afraid to let your books get a little messy, it's a sign that you're gaining knowledge and expanding your understanding of the world around you.
