I have a theory that the Tao Te Ching represents years.  There are 81 chapters, so after you're 81 you're beyond the book--but the only reason for this theory is that I  decided that if it were the case, I'd have a year to memorise a chapter.  Here's my chapter for this year:

Tao Te Ching by Lao Tzu Translated by Lin Yutang, Terebess Asia Online (TAO)

42.  The Violent Man

Out of Tao, One is born;
Out of One, Two;
Out of Two, Three;
Out of Three, the created universe.
The created universe carries the yin at its back
   and the yang in front;
Through the union of the pervading principles it
   reaches harmony.

To be "orphaned," "lonely" and "unworthy" is what men hate most.
   Yet the princes and dukes call themselves by such names.
For sometimes things are benefited by being taken away from,
And suffer by being added to.

Others have taught this maxim,
Which I shall teach also:
"The violent man shall die a violent death."
This I shall regard as my spiritual teacher.
