当下总是在变，但过去是固定的。
The present is always changing, but the past is fixed.
I have called this principle, by which each slight variation, if useful, is preserved, by the term Natural Selection.
"I don't need to be perfect. I just need to be good enough."
The house,the stars,the desert,what givethem their beauty is something that is invisible.
The silence between them was heavy, filled with unspoken words and unresolved emotions.
将心理过程从其适应背景中孤立出来就是完全误解了它们。
The dead are visible only in the terrible lidless eyes of memory.
Sustainability isn't an option; it's a responsibility we owe to future generations.
