NEW YORK (CBSNewYork) — Sarah Ferguson, the Duchess of York, is a best selling author.

“Giving confidence, I think, literally is so important for children,” the duchess said on The Couch. “I think education is the root out of poverty, because it teaches them survival, but also it is the root for a unique individual, and I think that is really important.”
