While the book is funny, it touches on a deep-seated fear: Imposter Syndrome. Nikki feels she doesn't belong at WCD. She feels like a fraud surrounded by rich kids. This is a universal feeling, whether you are starting a new school, a new job, or a new hobby. Watching Nikki overcome that fear is empowering for young readers.
Nikki’s biggest source of anxiety is her status as a scholarship student. She is terrified that people will find out she isn't rich. This insecurity is the driving force behind many of her early entries.
A significant theme of "Dork Diaries" is the search for identity. Nikki is trying to figure out who she is, where she fits in, and what she wants to be. Her diary entries reflect her journey of self-discovery.
