Katie Couric's Notebook: Making A Difference

Hi, everyone.

Who says one person can't make a difference?

Consider the story of James Simons. Three years ago, he decided American students needed help -- big help -- in math, so he founded Math in America here in New York to help train and retain teachers. Now there's a movement afoot to implement it on a national level.

Or take Janet Hanson. This former Wall Street executive founded an organization called 85 Broads -- which became a groundbreaking mentoring network for thousands of women around the world.

These are just two of the remarkable people we're celebrating on the CBS Evening News this week in a series we call "the American Spirit." These are good people doing great things, and we plan to spotlight more of them in the weeks to come.

With so much grim news in the headlines, we need to pay attention to what's right with America. People who really are proving there's truth to the old adage: where there's a will, there's a way.

That's a page from my notebook.
