What does it mean that America's scenery will eventually become the past?

No matter how beautiful the scenery is, it will eventually become the past: no matter how beautiful the past is, it has already passed. We cannot live in the past, but in the present.

Touching classic quotations:

1. No matter how beautiful the scenery is along the way, it will always disappear in an instant.

2. Andersen's fairy tales will eventually fail in reality.

3. If you lose it, you lose it. Don't expect it again.

I'm not afraid of waiting and pain, but I'm afraid I won't wake up if I don't get the result I want.

Life is like a ruthless meat cleaver, which changes our appearance.
