All my life I have been counting time. Back in high school I would count my time in hours, or even fractions of an hour. "Half an hour left of this class period." "Two more hours until school is out." In university I started counting in weeks. "This project is due in week six of the semester." "Only one more week of classes left." "Ugh, finals week." In the workplace I measure time in "man-days", but often from the larger perspective of months or quarters.
