On motivation: "I strongly believe that missionaries make better products. They care more. For a missionary， it's not just about the business.

我坚信倡导者能够创造更好的产品，因为他们关心的东西更多。对于一个倡导者来说，一个项目并不仅仅只是一个生意。他的事业与生意有关，而且必须把生意做好，但生意并非他做这件事情的原因。你做某一件事情，是因为它对你来说是有意义的，那才是你的动力。
Every man is his own God. If you give up yourself, who else will save you? A strong man can save.

心理学家必须避免一切形式的还原论。
