Men make their own history, but they do not make it as they please; they do not make it under self-selected circumstances, but under circumstances existing already, given and transmitted from the past.
人们自己创造自己的历史，但是他们并不是随心所欲地创造，并不是在他们自己选定的条件下创造，而是在直接碰到的、既定的、从过去承继下来的条件下创造。
The only constant in life is change, and we must embrace it.
I have always lived in my imagination; reality bores me.
君子不救人，不是没有能力，而是不愿意去做。
可持续发展不仅是一种趋势，更是一种责任。
