To me, fearless is not the absence of fear. It's not being completely unafraid. To me, fearless is having fears. Fearless is having doubts. Lots of them. To me, fearless is living in spite of those things that scare you to death.

有时候最勇敢的事就是在一切似乎都失去时继续前进。

The most powerful tool in science is not technology, but imagination.

如果你仔细观察，平凡的事物也会变得非凡。
