With each moment shorter than those before it, the psychological arrow of time knows only one direction.  Forward.

The days are long, the years are short - the past re-imagined, living only remembered.  Inward.

The future gives us hope, the past ... wisdom, our friends give us strength, our families, reason.  Upward.

Today is introspective, tomorrow pre-imagined, living only in our dreams.  Outward.

Thanksgiving takes pleasure in our posterity - I am humbled by that which is truly good.  Onward.
