I figure I've revised the hell out of my five books. I'm sure there are more improvements I can make and I will. But I have spent the last two weeks improving my music during this summer break. I've resung many songs on Volumes 9 and 11. I have always conceded that I'm not a singer. But that doesn't mean I can't try and make efforts to improve. I believe I have. The songs on Volumes 9 and 11 are great songs, and when I listen to them I'm amazed that I'm the one who wrote them. And now, with the improved vocals, they're even better. I will keep it up. It's what I do.
