You need to pick a project to start out so you have a goal, then from there it's just google searches for each individual part.

I started learning in High School because I wanted to create a game. I had learned a little bit of Java from a book my dad gave me, but I was kind of in the same spot as you at first where I didn't know how to do anything other than follow along with the book.

But once I sat down with my goal to make a game, and just started Googling stuff, that's when it started to click.

Python has easy syntax, so that might be a good place to start. You could google: "Python game library" and it would pull up something like PyGame. Then you could look up "Pygame tutorial" which would give you a baseline on how to set up a window, etc. If you have a hard time with Python fundementals, you could just google "python for loop" or "python functions".

That's pretty much what my learning process looked like: start with a goal, google how to get started, google each problem as it comes up. I still follow that same process to this day, and I have a CS degree now.

At the end of the day, it's a skill just like anything else. Just takes practice. I don't think anyone is too dumb to learn it, but it depends on how much you want it. If it's not worth the effort for you then you probably never will.
