1.5 billion people lack proper access to electricity. Many buy kerosene, which can cost 30 percent of their income. It sends millions of metric tons of carbon dioxide into the atmosphere every year. And often the lamp will fall over and catch the house on fire. So mothers hate it, but it's their only option.

My dream is to find individuals who take financial resources and convert them into changing the world in the most positive ways.

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.

When systems are broken, it's an opportunity for invention and innovation.

Our actions - and inaction - touch people every day, people we may never know and never meet.

Honour what is most beautiful about the past and build it into the promise of the future.

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.
