Annotating a book means adding your own thoughts, insights, and reactions to a piece of text while reading it. It is a way to interact with the book and make it your own. Annotating can be done using different methods, such as highlighting, underlining, writing in the margins, using sticky notes, or using colorful tabs. The purpose of annotating is to help you remember important parts of the book, dive deeply into the themes and ideas behind the book, and retain the story better. Annotating can also be a relaxing and creative pastime. It is a personal and customizable process, and there is no right or wrong way to do it. Some people annotate every book they read, while others only annotate certain genres or books. Annotating can be done using simple tools like a pen or pencil, or more elaborate supplies like colorful tabs, pens to color code annotations, and beautiful sticky notes.
