"History is not the past—it is the method we have evolved of organizing our ignorance of the past."
The only limit to our realization of tomorrow is our doubts of today.
"Books are the quietest and most constant of friends; they are the most accessible and wisest of counselors, and the most patient of teachers."
Books make great gifts because they have whole worlds inside of them.
历史不是机械的，因为人们有自由去改变它。
Innovation isn't about technology—it's about solving problems.
Man is the creator of his destiny, not its slave.
你不能让失败定义你，你必须让失败教会你。
