"Our entire life is made up of parts, with larger circles enclosing smaller ones. There is one which contains and surrounds all the rest; this extends from our day of birth to our final day. Another envelops the years of our youth. One cordons off all of our childhood in its circuit. Then there is a single year, containing in itself all the seasons by whose multiplication life is made up. A month encircled in a narrower circle. The smallest revolution of all is made up of a day, but even here we go from beginning to end, from sunrise to sunset… some say that a single day is equal to all days in resemblance; for even the longest stretch of time includes nothing you cannot find in a single day, namely light and darkness, and as we go on to eternity, days make these changes more numerous, but no different, whether they are longer or more extended. So each day should be ordered as if it were the last in the line, as if it finished off one’s life and made it complete."
