We have a responsibility to future generations to leave the planet in better shape than we found it.
我们有责任为子孙后代留下一个比我们发现时更好的地球。
A wise man said: before you speak， let your words pass through three gates. At the first gate， ask yourself， "Is it true？" At the second gate， ask "Is it necessary？" At the third gate， ask， "Is it kind？"
"A great story is one that changes you."
