The past is a shadow that follows us, but the future is a light that guides us.
过去是跟随我们的影子，但未来是引导我们的光。
史记
The more we learn about the universe, the more we realize how much we don't know.
The soul is placed in the body like a rough diamond, and must be polished, or the luster of it will never appear.
未来属于那些敢于相信不可能的人。
