Great question! I'm going to outline below what you can do at the start of electrical career to obtain the basics, but to be successful in any career the advice is the same: Never stop learning, always be open to feedback from others, ask questions about things you don't understand. We've all been at the beginning of our careers at some point, not knowing what to do. The advantage you have is the availability/accessibility of information.
If you have the opportunity to attend trade school while still in High School, focus on those classes for electrical. Two years of those classes should equal first year of apprenticeship training, which usually covers tools and safety for the job and basic Electrical principles.
If going during school hours is not an option, see what night classes are available to you. I took all my 4 years of classroom training for plumbing apprenticeship at night classes at the local technical school while working full time. The classroom training will give you the knowledge of the trade and help you understand the "why" of a lot of the work. Usually, the final year covers Code and you'll have to obtain the current NEC book. Having a thorough understanding of the code AND how your local Authority Having Jurisdiction (AHJ) interprets it, is essential.
If you're in a Union area, the Local will put you through apprenticeship classroom and On the job training (OJT.). If in non-Union, you'll have to find a company to work for. Some offer apprenticeship training, others only OJT.
Once you've got some experience, you'll be able to hone in on what type of electrical work you enjoy our are better at. Then you can pursue careers in those fields specifically, as there are a multitude of specializations.
