To know the value of one year -
ask the student who failed their final.
To know the value of one month - 
ask the mother of a premature baby.
To know the value of one week - 
ask the editor of a weekly magazine.
To know the value of one day - 
ask the wage earner with six children.
To know the value of one hour - 
ask the lovers who are waiting to meet.
To know the value of one minute - 
ask the person who missed the plane.
To know the value of one second - 
ask the person who survived the accident.
To know the value of one millisecond - 
ask the Olympic silver medalist.
