So, I've been wanting to get into programming for a while now. I know a little of HTML, CSS, Javascript and that's about it. I've fooled around with Python at one point. I can't decide on a language to learn - and I mean learn deeply. I've noticed that many languages have similarities. So once you learn one, learning others is much easier. I'm pretty much interested in programming anything that would benefit other people. OR games/apps, which I've heard Java is the best for. I'm really interested in learning one of the C languages, but I'm not sure which one. (Objective-C, C++, C#) If any of you guys could lead me in the right direction, I would very much appreciate it! Thanks!

First off, C# isn't part of the C family.
You forgot to mention C itself, the mother of pretty much all the other languages.
C, being one step above assembly, is very simple and does not have large amounts of features,
so if you want maximum performance, the smallest executable, C is the way to go.
It is used for kernels, embedded device drivers, device drivers, <good> malware, and some high performance apps.

Every language has it's own advantage, and C being the father and one of the most famous languages ever, in my opinion, should be your next language, I am saying this because you can practice programming without stepping on the complicated things like OOP (I know this from experience).
