Two Lines to the World

One of my favorite bands, Anberlin, has a song that starts with these lines:

"If I could write one letter to the world as we know it
I would list these rhymes that mean everything to me"

It got me thinking - if I had two lines to write down that would then somehow get sent out to the entire world, what would I say? Would I be my usual sarcastic self? Would I try to pass along some huge amount of wisdom? I spent a while thinking about it, and I think it would be just one line. I have a print of this framed on my dresser so it's the first thing I see in the morning and at night.

If you had 2 lines to say to the world, what would they be?
