How is playing an instrument or doing any other activities associated with a band for 40 hours a week not work? I'll grant that *some* artists today do very little work, but what about the bands that spend hours every week practicing their own instruments, writing new music, dealing with the business side of the band (contracts, recording issues, etc...), and touring? Just because musicians are largely spending their days doing something they enjoy doesn't mean it doesn't qualify as work. Developing high technical skills on an instruments, learning music theory, and learning to apply that theory to writing good songs can take years of practice, and can be just as difficult as something like software development if you choose to make it so.

Could you explain that using cars?
