Advice Needed Programming Languages

I find computer science a very interesting subject to study. I want to start learning a programming language.

My questions are:

Which language should I start with?
I know a lot of people might ask what exactly I am seeking to do, in order to give a precise answer to my question. But really, I just want to start off from somewhere. My goal is to learn a language and then to learn languages. I will study my first programming language to the maximum extent of my capabilities, and by then, I will hopefully have decided on what languages I am interested in. Of course, I will look back to this thread for reference.

Are there any HQ (or at least decent) sources that teach programming languages? If so, tell me about them.
Whether they be free or not, I will look into them. I would prefer them to be free, as I currently don't have any kind of income.

What is your reason for learning a programming language?
Whether it be for job opportunities or as a hobby or anything really. I am interested in what made you intrigued.

That is all. I have nothing else to add (for now?). I thank you if you took the time to read until here. Please don't hesitate to make a post answering only 1 out of the 3 questions I have. I am interested in any answer to any of those 3 questions.
