I shared an apartment with three jazz musicians at one point, and I was amazed at how dedicated they all were. One of them has now become a semi-star on the Jazz scene - but it didn't come cheap. On a normal day he would get up at eight, go to school, then head straight for some training session when he finished. After a quick dinner he would go out and play one or two jobs. On weekends he played 4 or 5 jobs and did some jam sessions or did recordings.<p>Being a jazz musician may sound like a cozy job, but to get anywhere it takes an 80 hour work week.
