A diary is a personal record where individuals write about their daily experiences, thoughts, and feelings. It often serves as a private space for self-reflection and can help improve writing skills. Diaries can be kept in various formats, including traditional notebooks or digital applications. Many people use diaries to track their goals, document significant life events, or express emotions. Some famous examples include the Anne Frank Diary, which provides insight into life during the Holocaust, and the Brontë sisters, who kept diaries that revealed their creative processes and personal lives.
