The Arrow and the Song
by Henry Wadsworth Longfellow

I shot an arrow into the air,
It fell to earth, I knew not where;
For, so swiftly it flew, the sight
Could not follow it in its flight.

I breathed a song into the air,
It fell to earth, I knew not where;
For who has sight so keen and strong,
That it can follow the flight of song?

Long, long afterward, in an oak
I found the arrow, still unbroke;
And the song, from beginning to end,
I found again in the heart of a friend.

Apropos of nothing; I've just always liked that poem and heard it again yesterday, so I thought I'd share.

Sometimes if you have an idea, you just have to let it fly and not worry about where it goes. You may never meet the people you've helped. But that doesn't make them any less helped.
