Inscription on the tomb of an Anglican Bishop

This is an inscription on the tomb of an Anglican Bishop in Westminster Abbey:

“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 I realize as I lie on my deathbed, if I had only changed myself first, then by example I might have changed my family. From their inspiration and encouragement I would then have been able to better my country,

And who knows, I might have even changed the world.”
