The most important thing is that you enjoy it, so you're taking the right steps. However, being a biologist is very broad these days and different biologists require a different set of skills. The most typical is working in molecular biology labs, where you perform PCRs, pipette different biological samples, and observe biological samples under a microscope. However, a biology degree can take you to other places! There are biologists who do computer modelling, manufacturing, project management, etc.
My advice is now that you know you like the subject, think about what you want to DO in the subject. If you like the idea of doing research in the lab, trying joining one or asking about it. If you think you'd want to do mathematical or computer modelling, take more advanced math and computer courses. If you want to build medical devices, engineering may be your path. Once you decide what you want to do, ask your guidance counselor or biology teacher which courses they recommend.
