摆脱困境的最好方法就是一开始就不要陷入其中。
The best way to get out of a situation is to never get into it in the first place.
Stay Hungry. Stay Foolish. And I have always wished that for myself. And now, as you graduate to begin anew, I wish that for you.
我没有任何特别的秘诀（用于开发新的证明）……这就是为什么做研究既具有挑战性又具有吸引力的原因。这就像在丛林中迷路，试图利用你能收集到的所有知识来想出一些新的技巧，并且如果运气好的话，你可能会找到出路。
I don't have any particular recipe [for developing new proofs] ... It is the reason why doing research is challenging as well as attractive. It's like being lost in a jungle and trying to use all the knowledge that you can gather to come up with some new tricks, and with some luck you might find a way out.
