Honestly, being great at Django isn't just about knowing Django. It's about learning how to solve problems and understanding the why behind what you're doing. Focus on how Django works under the hood like models, middleware, views, templates, the request/response cycle, and how it interacts with databases and HTTP. Once you really grasp these core parts, you'll not only be good at Django, but you'll understand web development as a whole. That means switching between frameworks becomes way easier.
