Will the nervousness about this project ever end? No, I imagine it won't. I might get a bit more comfortable as I go on, but the nervousness is here to stay. At least it's a good sign of how serious I take this. If I didn't care about any of this then I wouldn't be so anxious every time I get ready to post anything.
The more I read about music, the more I want to practice it. Someone once told me: "If you learn something new every day, the subject you learn about grows more and more exciting as you go." Or something like that. I paraphrase, but the point is still intact. I know I like music; I just have to keep reminding myself I do.
