I hear America singing by Walt Whitman,"Each singing what belongs to him or her and none else."(Walt Whitman)
This quote and the song both relate to the idea that every job is meaningful. Everybody has a job and all of the jobs are equally important in society.
A psalm of life by Longfellow connects well. "Trust no future, howe'er pleasant! Let the dead past bury it's dead! Act, -act in the living present!"(Henry wadsworth Longfellow)
The quote from Longfellow and the clip from wolf of wall street both connect to the idea of bury the past and live in the present.
