Everett Young is thinking about work.
At the moment all he sees is work as he looks out at the stars.
The ship is old, and there are always problems with something. The water, air, lights, hull, the list goes on and on.
Getting back home is certainly taking work; whether it is by finding enough energy to make the stargate work, or if it is by completing the Destiny's mission.
And then there are the people on this ship that require a lot of work; mainly a certain Scottish scientist.
He feels himself sighing. He has a lot of work to do.
