It’s not about being able to do something, it’s about being able to do it well.

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.

Life is difficult, and complicated, and beyond anyone’s total control, and the humility to know that will enable you to survive its vicissitudes.

保持好奇，保持活力。

有时候，最难的事情和正确的事情是同一件事。

Never give up, never surrender.

你国家睡不着觉是因为我。
