It's really easy to create a $1 billion company - you just have to solve a $10 billion problem.

Each one of us has the power to be the change we want to see in the world, making the world a better place.

Humans have always used our intelligence and creativity to improve our existence. After all, we invented the wheel, discovered how to make fire, invented the printing press and found a vaccine for polio.
