I don't believe in pessimism. If something doesn't come up the way you want, forge ahead. If you think it's going to rain, it will.

Concerning the gods, I cannot know either that they exist or that they do not exist, nor what form they might have, for there is much to prevent one's knowing: the obscurity of the subject and the shortness of man's life.

The only real mistake is the one from which we learn nothing.

最好的决策是结合数据和直觉做出的。

写作是耐心和固执的问题，而不是天赋。
