The real problem is not whether machines think but whether men do.

The person who tries to live alone will not succeed as a human being. His heart withers if it does not answer another heart. His mind shrinks away if he hears only the echoes of his own thoughts and finds no other inspiration.

The best way to predict the future is to invent it.

The real challenge is not growing more, but growing better with fewer resources.

实现梦想的唯一方法是每天努力工作。
