Don't make promises you can't keep. But those are the best kind.
不要许下做不到的承诺，但是我们做不到的承诺往往是最好的。
The best way to be a man of his word may be never making any promise.
And the best way to avoid being disappointed is never having any hope or wish for the future.
But those are the best things, those are what we strive for.

To learn from each other, to share with each other, to make progress collectively, and to attain great achievements.
