One of my favourite scenes in the movie Dancer in the Dark is the song/dance movement in the factory where Selma works. She is going blind, so her world is made up of sound and movement, and this piece takes the rhythmic sound of the machines as percussion for the music. It's extraordinary.
Does your routine work have rhythm? Does it have sounds? Is there a pattern to the sounds? Does it have motion? If you were to choreograph your job, how would you make a dance out of it? Choreography is a creative art, and yet it is made up of a carefully considered routine timed to the second and practiced to perfection. Yet the result is anything but boring.
Do your hands do a job without your mind really needing to think about it? Watch your hands - how amazing is that skill?
