Time is the invisible material in all my works.

我写作不是为了被爱，而是为了被理解。

质量比数量更重要。一个全垒打比两个二垒安打好得多。

Nothing is a waste of time if you use the experience wisely.

Take long walks in stormy weather or through deep snows in the fields and woods, if you would keep your spirits up. Deal with brute nature. Be cold and hungry and weary.

有什么方法可以解决刚才提到的这些焦虑呢？是有的。我想提出几项，先说“功绩主义”，也就是相信每个人的地位忠实呈现他的能力，我认为这种想法太疯狂了，我可以支持所有相信这个想法的，无论是左倾还是右倾的政治家，我同样相信功绩主义，但我认为一个完全彻底以能力取决地位的社会，是个不可能的梦想。

Sustainability isn't an option; it's our responsibility to the next generation.
