The Gates Foundation has learned that two questions can predict how much kids learn: 'Does your teacher use class time well?' and, 'When you're confused, does your teacher help you get straightened out?'

To create a new standard it takes something that's not just a little bit different. It takes something that's really new and really captures people's imagination. And the Macintosh, of all the machines I've ever seen, is the only one that meets that standard.

As I see it, there are two great forces of human nature: self-interest, and caring for others. Capitalism harnesses self-interest in a helpful and sustainable way, but only on behalf of those who can pay. Government aid and philanthropy channel our caring for those who can't pay. But to provide rapid improvement for the poor we need a system that draws in innovators and businesses in a far better way than we do today.
