你的黑暗无法褪去是因为我。

Sometimes the hardest thing and the right thing are the same.

If you're not stubborn, you'll give up on experiments too soon. And if you're not flexible, you'll pound your head against the wall and you won't see a different solution to a problem you're trying to solve.

Great things never come from comfort zones.

我们生活在一个影子的世界里，我们自己也是影子。
