实现明天理想的唯一障碍是今天的疑虑。

We cannot always build the future for our youth, but we can build our youth for the future.

There are things that happen and leave no discernible trace, are not spoken or written of, though it would be very wrong to say that subsequent events go on indifferently, all the same, as though such things had never been.

回收应该是最后手段而非首选方案，更好的设计应该放在第一位。

我们创造的空间必须激发创造力和联系。
