Haven't quite finished reading California, but this line hit me as meaningful. And it strikes me that we do an awful lot of thinking to the past. And if we aren't thinking in the past, we're looking ahead. I think we need to dwell on the present more...just a thought.
"Time moved forward, but the mind was restless and stubborn, and it skipped to wherever it pleased, often to the past: backward, always backward." California, by Edan Lepucki
As I thought about this, I recalled the last line of The Great Gatsby (below). Wow, same thought, so many generations apart. We humans really don't change.
"So we beat on, boats against the current, borne back ceaselessly into the past." The Great Gatsby, F. Scott Fitzgerald
