I've learned piano in high school for a semester. There, I acquired a bit experience on it, or at least enough to make me play simple songs. Its been almost 2 years since that course I took, but I don't know where to continue. It just seems there are too many things I could practice, but I have no idea if I have the knowledge required to study them. What should I do? How do I find what "level" I am? I also have to note that I'm by myself, I don't have enough money to pay a course or hire a teacher.
I don't really have a defined objective. I just want to be capable of having a extensive collection of songs which I can play myself, complicated and simple ones. Other than that, I can't define a goal for myself.
