The desert teaches patience, silence, and the art of listening to the whispers of time.

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.

「人生就只活这么一次。」「错，我们一生只死一次，剩馀的每天都在生活。」

I treat it like every day is a new challenge, and I’ve got to get better every day.

Every life is extraordinary.
