孔子说：“年轻人值得敬佩，怎知后代不如今人？四五十岁还默默无闻的人，就没什么前程了。”
"Never stop learning, because life never stops teaching."
We carry our homelands within us, even as we leave them behind.
I don't want to be a teacher. I want to be a friend.
Innovation is the key to unlocking a sustainable energy future.
One never reaches home, but wherever friendly paths intersect the whole world looks like home for a time.
