When I was a young man, I wanted to change the world. I found it was difficult to change the world, so I tried to
change my nation. When I found I couldn't change the nation, I began to focus
on my town. I couldn't change the town and as an older man, I tried to change
my family. Now, as an old man, I realize the only thing I can change is
myself, and suddenly I realize that if long ago I had changed myself, I could
have made an impact on my family. My family and I could have made an impact on
our town. Their impact could have changed the nation and I could indeed have
changed the world.
