Music may seem really glamourous if you don't do it for a living. It can be, but mostly it's A JOB. I think that you're confusing wanting to become a big star with wanting to make a living doing what you love. Being a working musician has much more in common with being a roofer than it does with being a star.
This is exactly what my old teacher told me. His story was actually kind of sad considering how talented he is. He does fine, but if you can be that good and struggle, what would a guy like me do?
