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.
The spirit is the life that itself cuts through life.
Sustainability isn't an option; it's a necessity for the survival of our industry.
——《致鲁赛尔函》（1906年11月8日）
Innovation is not just about technology; it's about mindset and the willingness to challenge the status quo.
一只系得妥帖的领结，就是人生认真的第一步。
领导力就是让他人因为你的存在而变得更好，并确保这种影响在你离开后依然持续。
