出處:1876年3月10日，貝爾第一次通過他發明的電話在寢室向在實驗室里的助手沃森說的一句話。

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.

以平和的態度與人相處，但貴在有堅定不移的原則。對待自己須剛正，但貴在處事圓融通達而不拘泥。

What we need to do is always lean into the future; when the world changes around you and when it changes against you—what used to be a tail wind is now a head wind—you have to lean into that and figure out what to do because complaining isn't a strategy.
