The goal of singing a song is not to reach the end as quickly as possible. It is a state of creating harmony, beauty, growth and understanding. The goal of work, as a sacred art, is to use the need for a product or service to develop the greatest possible power on the object, and the users. Sacred work puts the mind on service to the heart as well.
If I knew for certain that I should die next week, I would still be able to sit at my desk all week and study with perfect equanimity, for I know now that life and death make a meaningful whole.
