I am wondering if my goal is realistic and I realize that some songs take very little time to master although others might take a few weeks. I have been through Fundamentals 1 and 2, and currently in Country 1. Is it realistic for me to be able to master at least one song per week? I would like to get to the point where I have about 30 songs mastered by next summer. Having said this, also, is it ok to start working on a second song as you are close to mastering the first. For me this avoids being bored by working on multiple songs. Any thoughts?
