写作就是抵抗，抵抗就是存在。
"To write is to resist, to resist is to exist."
保持渴望，保持愚钝，但最重要的是保持谦逊。
In the end, we only regret the chances we didn't take.
So given a Time Turner, I would tell my 21-year-old self that personal happiness lies in knowing that life is not a check-list of acquisition or achievement. Your qualifications, your CV, are not your life, though you will meet many people of my age and older who confuse the two. Life is difficult, and complicated, and beyond anyone’s total control, and the humility to know that will enable you to survive its vicissitudes.
世界只给予我一次，不是存在一个又感知一个。
