A Challenging Thought
I attended a webinar on how to make it happen teaching private music lessons. I think it's called Music Money Formula, which I recommend you check out. One thing they said on the webinar is that musicians, being creative people, think they need to create solutions to problems that have already been solved when it comes to business.
When you try to create a solution to a problem, you get discouraged when it doesn't work out, when all along you just needed to do what others are successfully doing. Just emulate what other people are doing successful. Put your creative energy into stuff that really matters: your music.
