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.

People have to understand that unless social enterprise is experimental, it will not succeed in making a difference.

Monsters will always exist. There's one inside each of us. But an angel lives there, too. There is no more important agenda than figuring out how to slay one and nurture the other.

There are probably no more market-oriented individuals on the planet, than low income people.

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.

So many low income people have seen so many failed promises broken and seen so many quacks and sporadic medicines offered to them that building trust takes a lot of time, takes a lot of patience.

Sometimes the most important things that we do are things we cannot measure.
