Have you ever heard a story that was so cool you couldn’t help telling everyone you met about it? Something you knew and wished that everyone else did too?

That’s how I feel about the people whose work I get to learn about through the Gates Foundation. Every day, around the world, they save lives and help people lift themselves out of poverty. Some are scientists. Others are educators, nurses, midwives, or advocates. Their work is so inspiring to me that I’ve committed virtually all of my wealth to supporting it.

These workers at Enviro Loo in South Africa produced a new toilet that has transformed sanitation at public schools, making it much easier for students to attend.

When I see how much passion people like Josephine have for helping themselves and their neighbors, I’m inspired to help too. I hope these stories will be as inspiring for you as they are for me.
