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.
The moment you stop trying is the moment you start dying.
要是命运将会使我成为君王,那么也许命运会替我加上王冠,用不着我自己费力。
