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.

I was never afraid of failure; for I would sooner fail than not be among the greatest.

Failure is not scary; what's scary is losing the ability to learn from it.

Go for it now. The future is promised to no one.

我不相信“完成”——艺术总是在演变。
