Katie Couric's Notebook: Eurnice Kennedy Shriver

Let me win. But if I cannot win, let me be brave in the attempt.

With those words, Eunice Kennedy Shriver opened the first Special Olympics. It was 1968, and a crowd of about 1,000 people were gathered in Chicago's Soldier Field - about as many spectators as there were athletes.

Today, three million potential Olympians are training in 180 countries and Special Olympics is an international symbol of the hurdles disabled people have cleared - the heights they have reached since she began her mission.

As her brother, President John F. Kennedy, once said, "to whom much is given, much is required." But for Eunice, working with mentally disabled people wasn't an obligation. It was a true passion and a calling.

She changed minds, laws, and lives along the way.

Today we say goodbye to the lady, but the legacy is eternal. The lesson that bodies and minds may have limitations, but spirits never do.

That's a page from my notebook.
