Musicians, have paid or continue to ''pay their dues''. Non-musicians haven't.

It's also an inherent desire, as strong as eating, sleeping, pro-creating...to make, play and create music.

IMHO, the combination of the above two points, constitute the difference between a true musician and a musician wanna-be.

It's almost like the difference between an amateur photographer and a professional photographer. The amateur photographer views a scene and says '' Gee, that would make a nice picture.'' The professional photographer takes the picture.
