I'm not sure how old you are and where you are in your schooling journey, but assuming that you're in your high school, the most effective way to start your career in electrical engineering would be to get good grades in your classes. Getting good grades will give you the opportunity to take AP courses (assuming that your school offers them), such as AP Physics, AP Calculus, etc that you'll need to be a successful electrical engineer.
Once you have good grades in your classes, your next step is to get into a college or university where you can take classes that a bachelors degree in electrical engineering would require. It's also important that you get good grades in college, as when you apply for electrical engineering jobs, the recruiters will definitely look at it. During summer, the best way to spend your time would be to get internships at companies that hire electrical engineers. This way, when you graduate, you'll have the option of getting an electrical engineering degree.
Oh, I skipped the part where after you get a bachelor's degree, you'll have the option of working or getting a masters (or higher) degree, but I think once you have a bachelor's degree, I would argue that you are an electrical engineer. :)
I hope this was helpful! I wish you the best!
One thing I'd suggest additionally, though, is that you can learn and practice a lot of electrical engineering knowledge yourself as a hobby - that sort of thing can set you up ahead-of-time so you can learn faster and understand better - and maybe help you get better grades in your electrical engineering studies. Maybe you're already doing this, and if so, great - but if not, try to get yourself an educational electronics kit or just some basic circuit components and start building things - start with very basic circuits and start getting an intuitive feel for resistance, capacitance, inductance, the properties of AC vs DC signals and much more - the more you learn, the more complex you can make your projects.
The internet is a great resource to build and develop your personal interest in the subject. Look for higher education colleges or universities with courses. You can also look for companies with trainee programs or apprenticeships.
Showing you have a passion for the subject and have learnt abut the subject from the internet or from books and magazines will give you a better chance to succeed in interviews.
