Studying existing component systems is a great starting point. You have to imitate and respect the systems that already exist before you can innovate on new things from scratch. I'd recommend starting by reading, building with, and imitating the most well-known frameworks for some personal projects. You can also find some good Figma projects to get started with on each of these.
