Thanks for the thoughtful comments, Jane.  I agree with your assessment about the "past as predictor" idea - what we have done may influence what we do into the future, but it sure does not mean we'll do the same thing.  If this idea of "past as predictor of future" really worked, it would reflect a significant inability on our part to grow, learn, and change.   I think we are generally more capable than that apocryphal figure who continues to beat their head against that concrete wall.

Of course, we also have "No matter where you go, there you are" by as stated by either Confucius or Buckaroo Banzai.  We do travel with our past - it just does not have to determine our route or where we end up.   As Bob Newhart beautifullly stated when playing a therapist working with a young woman who was experiencing angst "Just STOP it" ... words to live by:)

Appreciating what we have or had is a bittersweet, but essential thing ... since things always change and we humans are constantly adapting to new things and new environments.   Sometimes I wish I were back on the farm as a wee lad, with the knowledge of all that was to come so I would enjoy those long-ago moments a bit more:)
