As I stated in my last post, programming is the act of communicating to a computer system a certain set of instructions with the intent of gaining certain desired results.
As in everyday life, when you communicate to other people, you use words or written text, and those come under the umbrella of a specified language, English, Spanish, Chinese, etc. Computer languages are no different.
There are different languages to fit different needs.
You want to create the structure of a website? Then you will use HTML5.
You want to style that website? Then you will use CSS3.
You want to create a blog? Then WordPress and PHP is what you'll use.
Right about now, your head feels like it's about to explode.
Don't stress, it's common to feel intimidated about this time. One of the most common fears and concerns for a beginning programmer is that they have to learn everything about every language out there. Let me say this first and foremost, you will never know everything, and no one will ever expect you to.
The more and more you try to get familiar with every language, the farther you get from being competent in any of them.
I know there's Python, Ruby, Java, C# out there...and who knows, maybe, just maybe, I can go there, but I'm not going to stress like it's the end of the world...and that's the attitude I suggest you have to.
