To understand the mind, we must first understand its evolutionary purpose.

世界上最重要而美好的事情是：人们并非一成不变，尚未定型——而是永远处于变化之中。

译文：什么人可以称得上享福之人呢，当然是能读书且从中受益的人；什么人可以称得上创家立业的人呢，当然是能够教育出子孙的人。赏析：天下第一好事就是能读书，能读书说明思维活跃，头脑清晰，身体健康，而书中的道理也能从中获得。任何事业上的成功都弥补不了教育孩子失败的遗憾。身为父母，最大的成功，应该是教育出一个温暖有爱，品行端正，身心健康的孩子。

"The world is full of obvious things which nobody by any chance ever observes."

Safety must remain our top priority in every operation, every day.

So what I want to argue for is not that we should give up on our ideas of success, but we should make sure that they are our own. We should focus in on our ideas, and make sure that we own them; that we are truly the authors of our own ambitions. Because it's bad enough not getting what you want, but it's even worse to have an idea of what it is you want, and find out, at the end of the journey, that it isn't, in fact, what you wanted all along.
