The best moments in our lives are not the passive, receptive, relaxing times... The best moments usually occur if a person's body or mind is stretched to its limits in a voluntary effort to accomplish something difficult and worthwhile.

You have to see failure as the beginning and the middle, but never entertain it as the end.

"Every observation we make is a step closer to understanding the cosmos."

释义：他认为气不仅是万物的起源，也是万物的归宿，万物在气的循环中生生不息。
