Facebook was founded on February 4, 2004. On February 5, we were feeling pretty confident, even from observing the first few hours of usage. Students used it like crazy. They'd sign up then spend the next 3-4 hours on it. Then we'd go to lecture hall and see it on every computer screen there.
I can't apply $3 billion in capital to the tech industry. It wouldn't work. But in infrastructure, education, I can make a real difference. I can change someone's life, for the better, permanently. If I can improve a kid's education, I can increase their salary later on and for decades.
