Sometimes, the hardest battles are fought within the confines of our own minds.

To feed the world, we must first understand it.

"It's important to write about difficult subjects in a way that children can understand."

所有真正伟大的思想都是在行走时孕育的。

大海不会奖赏那些过于焦虑、贪婪或急躁的人。

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

The world is a book, and those who do not travel read only one page.
