Food for thought from "Time and the Art of Living" by Robert Grudin,
Chapters 12 and 13 (the last):

XII.16  In the heat of action, the mere ability to remember our principles, our goals and the specific reasoning behind the course we have taken is an element of courage.  Memory is fear’s first victim.

XII.22  Journals can serve many purposes – creative, professional, psychological; but no matter why we keep them, they are a boon in locating our vagrant awarenesses within the broader expanse of time.  And indeed they can slow time down by reminding us, again and again, of the breadth and fullness of a single day.

XII.23  In writing your journal give primary attention to detail; for it is detail which organizes and preserves experience for your future self or some other reader.  ///  I failed to record how we looked, what we saw, the minor eccentricities of circumstance which gave special character to a day.  I mistakenly assumed that one could discuss the heart of things without discussing the surface of things.

XIII.1  We love only when we love across time, when love offered is love remembered and love promised.

XIII.4  Happiness may well consist primarily of an attitude toward time.  Individuals we consider happy commonly seem complete in the present.  Yet paradoxically they give an impression of permanence and consistency.  They do not change greatly from day to day.  They choose and patiently develop lengthy projects.  They love remembering past experiences and making plans; they speak of past and future as quiet extensions of their own being.
