Thanks. I hear you. One side of me says just have fun expressing myself with the skills I'm developing. Another side puts pressure to get good enough to produce a song that more than my Ms. and instructor likes.
Funny, I was working on an original tune I could hear in my head. But it just wasn't coming together and I was going to give up. Then my instructor ( http://www.jamiehoover.net/ ), "relax, make a list of what you like and don't and fix them." Well, I had no confidence this song would get better. But after two weeks of critical listening, re-tracking some stuff, shortening the song, etc. it slowing kinds came together and I was like "wow."
