Over the years I’ve taken part in some amazing celebrations. As a native Atlantan, I remember the moment in 1990 when we heard the announcement on the radio that the Summer Olympics were coming to our city. People began honking car horns and spontaneously hugging strangers in the streets. Five years later the Atlanta Braves won their first (and only) World Series title, and my friends and I stayed up all night toasting our champions. Then there was the moment when my wife and I learned that she was pregnant—after years of hearing that this was not likely to happen. Tears ran down our faces as we embraced one another.
