可持续性不是一种选择,而是我们对下一代的责任。
Knowledge is the most valuable resource in the universe.
The human voice is the most beautiful instrument of all, but it is the most difficult to play.
Never try to discourage thinking, for you are sure to succeed.
We build not for today, but for how today will be remembered tomorrow.
The only way to do great work is to love what you do.
