永远不要停止学习；当你认为自己无所不知的那天，就是你开始落后的那天。
Never stop learning; the day you think you know it all is the day you start falling behind.
The future belongs to those who believe in the beauty of their dreams.
"I write for kids because I was a kid who needed books."
I was as hollow and empty as the spaces between stars.
成功在于坚持和永不放弃。
