Then you should give up on building an operating system. At least for now.
I would say the first step is to learn a programming language. Any programming language. C is hard, and probably not a wise starting point for you in that case.
Get a good book, do exercises and do programming projects to learn a language. If you can't do it on your own, take some lessons.
Then start getting into computer science. You will need it.
Only when you feel you have a really good grasp on computer science can you think of building an operating system.
