把这一句，留给此刻的你
Whether you are an astronomer or a life scientist, geophysicist, or a pilot, you've got to be there because you believe you are good in your field, and you can contribute, not because you are going to get a lot of fame or whatever when you get back.
无论你是天文学家、生命科学家、地球物理学家，还是飞行员，你必须在那里，因为你相信你在自己的领域很优秀，你可以做出贡献，而不是因为你回来后会获得很多名声或其他什么。
