Tomorrow's regret is today's fear.

Today's fear is denial:
A desire to ungrow, and unlearn the lessons from the future;
A desire to lay back on soft pine needles, in the comfortable warmth of sunny dispositions and breezy conversations;
A desire to unhear cries for help and pleas for progress;
A desire to unsee wanton disregard and ruinous neglect.

Tomorrow's regret is today's fear.
