Everybody feels this way. Sometimes working with music is frustrating because it feels like the path you are on must be built brick by brick before you can even walk on it, when all you want to do is just walk on it. This is part of the madness of modernism, where originality is more important than any other aspect of the music. I have found this mindset to be a shackle - IF - your problem is continuity. When I give up trying to be original and just write, I necessarily lose many inhibitions. And this means more music. and the more music I write, the better it becomes and the more fun it is to write. That's the way I look at it.
