As wave is driven by wave
And each, pursued, pursues the wave ahead,
So time flies on and follows, flies, and follows,
Always, for ever and new. What was before
Is left behind; what never was is now;
And every passing moment is renewed.

As I was walking yesterday, these autumn leaves scattered on the ground reminded me of renewal, and the above poem by Ovid from The Metamorphoses, book 15.
