问题不在于事物是否存在，而在于它是否具有能够在没有我们的情况下存在的本质。

我不会因为累而停止，我会因为完成而停止。

"And this I believe: that the free, exploring mind of the individual human is the most valuable thing in the world. And this I would fight for: the freedom of the mind to take any direction it wishes, undirected."

Every challenge is an opportunity to learn and improve.
