You are always a valuable, worthwhile human being — not because anybody says so, not because you're successful, not because you make a lot of money — but because you decide to believe it and for no other reason.

任何实验的价值和效用都取决于材料是否适合其使用的目的。

释义：只有经过艰苦的努力和考验，才能发现或创造出价值重大的事物。

To curate is to care—for the art, for the artists, and for the audience.
