Ai Wei Wei answers the Proust Questionnaire.

What is your favorite journey? My favorite journey is a journey which you walk alone but at the same time you know somebody is waiting for you at the end. It’s the perfect journey—it doesn’t matter how difficult, how dark, or how protracted, as long as you believe there is someone waiting for you there. That makes a journey different. Our life has no purpose unless we believe there is someone waiting there.

What do you consider your greatest achievement? I never did anything unforgivable. Whatever I did can be forgiven.
