Living for the End
Words have their own rhythm which we abandon when we focus too much on grammar and what is technically correct. The colons in this stanza are not used correctly; however, they exist to contrast and enhance the message that for many life is a race to the next point often without recognition of where they were. A colon draws a direct relationship between two points; here the colon shows that without existing for now there is no relationship with then.
Like ants they scurry across the face of the planet:
Wake up: eat.
Eat: commute to work.
Work: take a lunch.
Lunch: return to work.
Work: commute to home.
Home: eat.
Eat: Sleep
Repeat
