海洋对所有人都是共有的，因为它是如此无边无际，以至于无法成为任何人的财产。

The best advice I can give to aspiring filmmakers is to never give up on your dreams.

And I hope you will come back here to Harvard 30 years from now and reflect on what you have done with your talent and your energy. I hope you will judge yourselves not on your professional accomplishments alone, but also on how well you have addressed the world's deepest inequities…on how well you treated people a world away who have nothing in common with you but their humanity.
