书籍是最安静且最恒久的朋友。
"Books are the quietest and most constant of friends."
Your most unhappy customers are your greatest source of learning.
The market needs solutions, not just products.
You cannot make yourself feel something you do not feel, but you can make yourself do right in spite of your feelings.
世界不是一个需要解决的问题；它是一个我们所属的生命体。
Life is not about waiting for the storm to pass, but learning to dance in the rain.
人类进化的故事远未结束。
你不能让失败定义你，你必须让失败教会你。
