体育教育的目标是发展健全的身体，作为健全心智的工具。

I can never be safe; I always try and go against the grain. As soon as I accomplish one thing, I just set a higher goal. That's how I've gotten to where I am.

Every project is a new adventure, a new challenge.

"We are still in the early days of understanding how to build truly intelligent systems."

未来无人知晓，正因如此，我们应该活在当下。
