I know next to nothing about Mrs. Edwards except that her husband was a politician. I saw this quote on Breathless Expectation, a blog I have only reciently discovered.
"The days of our lives, for all of us, are numbered, we know that. And yes, there are certainly times when we aren't able to muster as much strength and patience as we would like. It's called being human. But I have found that in the simple act of living with hope, and in the daily effort to have a positive impact in the world, the days I do have are made all the more meaningful and precious. And for that I am grateful." -elizabeth edwards
