I was reading about it and I do not like the idea of just improving others ideas. Should I become an engineer?
I think you'll need to get used to that; "standing on the shoulders of giants," and all that. Unless you already have a clear history of revolutionary inventions, you need to be thinking about making evolutionary changes to things. This is not a bad thing, since many of what appear to be revolutions are, in fact, evolutions that included a small, game-changing nugget. The original Apple II was not that revolutionary, in itself; what set it apart was a software interface that allowed the user to directly interact with the computer in an English language programming system.
