Editor's note: Among the tombstones in the basement of the world-famous Westminster Abbey in London, there is a world-famous tombstone. In fact, this is just a very ordinary tombstone, with rough granite texture and ordinary shape. But everyone who has been to Westminster Abbey does not have to pay homage to the once-prominent former British kings, or to pay homage to world celebrities such as Dickens and Darwin, but no one fails to pay homage to this ordinary tombstone. For a long time, the inscriptions on it have deeply shocked generations of descendants.

When I was young and free and my imagination had no limits, I dreamed of changing the world.

As I grew older and wiser, I discovered the world would not change, so I shortened my sights somewhat and decided to change only my country. But it, too, seemed immovable.

As I grew into my twilight years, in one last desperate attempt, I settled for changing only my family, those closest to me, but alas, they would have none of it.

And now, as I lie on my death bed, I suddenly realize:

If I had only changed myself first, then by example I would have changed my family. From their in inspiration and encouragement, I would then have been able to better my country, and who knows, I may have even changed the world.
