How to Get Started in Computer Science [closed]

Question

I am wondering how to get started in studying theoretical computer science and how to apply it to my programming. I am fairly comfortable with basic programming, having been programming in mainly C++ but also Java for the past couple of years, so I don't necessarily need an introduction to programming.

What I am looking for to start is perhaps something fairly broad, so that it gives a wide overview of computer science, as I don't know exactly where I want to study within it yet. But it could also be nice to have directions of where to look to continue studying a specific aspect of it. However, this is just what I think could be helpful, and I am open to any recommendations.
