A method of solution is perfect if we can foresee from the start, and even prove, that following that method we shall attain our aim.
如果我们从一开始就能预见，甚至证明，遵循某种方法我们将达到我们的目标，那么这种解决方法就是完美的。
我不害怕死亡，我害怕不去尝试。
Do not follow where the path may lead. Go instead where there is no path and leave a trail.
No arts; no letters; no society; and which is worst of all, continual fear, and danger of violent death; and the life of man, solitary, poor, nasty, brutish, and short.
多元化不仅仅是一种策略，它是一种必要。
每一次挫折都是卷土重来的铺垫。
技术应该为人类服务，而不是反过来。
