In the realm of computational complexity, every problem is a universe waiting to be explored.

Success is not final, failure is not fatal: It is the courage to continue that counts.

未知不是要害怕的东西，而是要拥抱的东西。

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.

人生最大的荣耀不在于从不跌倒，而在于每次跌倒后都能站起来。
