What are the steps I need to take after high school to own a good electronic business?

Exzavier, I'd suggest that after High School you should look at getting a college degree in electrical engineering or computer engineering. This will help to give you the solid foundation in electronics, as well as train you on how to recognize new changes in electronics on the horizon. This is definitely important, because the field of hardware changes so quickly each year. With that degree in electrical engineering, you should be better suited to starting your own business, and hiring the talented engineers you would need to run that business. To get your degree, you will need to have some good math and physics skills - the physics is for understanding how computers work, and the math is for doing your engineering calculations, and will also come in handy when you're building your business (getting the numbers wrong could cost you millions of dollars and that's not an expense you can accept). Stay focused on your studies in High School to get yourself on the right path!

After your college degree, then you should have a better idea of exactly what type of business you would want to build. Then you could work for another successful entrepreneur for a while to gain some experience, or you could try to raise some money to start your own business right out of college. It will depend somewhat on what the market conditions are like when you leave school - will there be many investors ready to invest or will it be a recession and make it difficult to raise funds?

p.s. Most college programs will have an electrical engineering or computer engineering department. You should be looking for one that boasts of the brand name companies its graduates work at, and which has a pretty broad array of engineering classes. It would also be good for you if the school offered access to business classes, given your interest in entrepreneurship. You should check out your high school's college office to start figuring out what sort of schools might be good targets for you, and how you can find ways to raise the money to invest in college.

I think you should look on google or try to research information in that career field.
