Dignity is more important to the human spirit than wealth.

When we deny the poor and the vulnerable their own human dignity and capacity for freedom and choice, it becomes self-denial. It becomes a denial of both our collective and individual dignity, at all levels of society.

Human beings tend not to spend money on health preventionally. We tend to spend it on top treatment.

The human spirit is extraordinary. If we give the 3 billion people who live in poverty the opportunity to change their lives, they will. For too long, we've looked at needing to "save" these people - with an emphasis on "these people" - rather than removing the constraints keeping them from solving their own problems.

Poverty is too complex to be answered with a one-size-fits-all approach, and if there is any place that illustrates that complexity, as well as a better way forward, it is Rwanda.

All people deserve access to health at prices they can afford.

Why do some people stop growing at age 30, just going from work to the couch and television, when others stay vibrant, curious, almost childlike into their nineties?
