The only way I know of is to hire on as an apprentice, keep your eyes open, work hard, and learn all you can.
If you can afford to, take a course, the kind where you get about 50% hands on (shop time), at a trade school or community college first.
It really helps if you have a natural interest in electrical equipment and systems.
