The essence of mathematics lies in its freedom.

不只是国家有染的问题，对士而言也有受到熏染的问题。 

未经审视的生活不值得过。

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.
