审判自己比审判别人要难得多啊！你要是能审判好自己，你就是一个真正有才智的人。

I will tell you what I will do and what I will not do. I will not serve that in which I no longer believe whether it call itself my home, my fatherland, or my church: and I will try to express myself in some mode of life or art as freely as I can and as wholly as I can, using for my defence the only arms I allow myself to use—silence, exile, and cunning.

真相往往令人不适，但必不可少。

Innovation is not just about creating new products, but also about reimagining how we serve our customers every day.

我不让失败定义我，我让它磨砺我。
