Tomorrow
Time, the absolute factor in human life, has been measured in a linear fashion, as expressed in phrases such as "a little while ago", "now", and "a little later", "yesterday", "today", and "tomorrow"; "last year", "this year", and "next year"; or "past", "present", and "future". From a linear perspective on time, a lifetime can be divided into before and after, with now as the center; into yesterday and tomorrow with today as the center; and into past and future, with the present in the middle.
