可持续性不是一种选择，而是我们对下一代的责任。
Sustainability is not an option—it's a responsibility we owe to the next generation.
"The only thing that is truly boundless is the human spirit."
The mind is everything. What you think you become.
译文：要有所获取，就一定要有所舍弃，要有所禁止，就一定要有所宽容。赏析：人生没有完美的事情，世间的所有好事不可能都让我们占完，总是有舍才有取，有失才有得。禁止就是不可为，宽容就是我们对待别人要圆滑。
