Innovation is not achieved overnight, but through continuous accumulation and breakthroughs.

要养活世界，我们必须先理解它。

The only limit to our realization of tomorrow is our doubts of today.

The past is always tense, the future perfect.

That is what learning is. You suddenly understand something you've understood all your life, but in a new way.

一切幸福都绝非没有忧虑和烦恼，而一切逆境也绝非没有慰籍与希望。
