I couldn't draw one up but I can read them fine. I'm good on
  comprehension of subject matter -, poor on production smile

  Oh the numbers are how many posts for that time period. I
  treated it like a "google for my brain"... or at least a google
  for stuff I've produced. I have SO many 3x5 spiral notebooks to
  go through, typewritten papers to retype in... thousands of
  index cards to scan...

  anyway... it's disorganized and the only context is that of
  date/ and a google-type search. It took me a long time to come
  up with such a simple system.

  The left is "anniversary" - part of a hypothesis I have that I
  tend to have similar types of thought processes around the same
  time each year, the theory being that since I'm a part of this
  planet and locked in its cycles, it's likely my thinking
  processes will be similar from year to year around the same
  time, and that I'll produce similar writings each year, without
  realizing I've done them before.

  Seems to hold somewhat true, although I haven't given it a full
  study yet.
