Do What You Wish

"[Bastian] asked ' "Do What you Wish." That must mean I can do anything I feel like. Don't you think so?'
All at once Grograman's face looked alarmingly grave, and his eyes glowed. 'No...it means that you must do what you really and truly want. And nothing is more difficult.'
'What I reallly and truly want? What do you mean by that?'
'It's your own deepest secret and you yourself don't know it.'
'How can I find out'
'By going the way of your wishes, from one to another, from first to last. It will take you to what you really and truly want.'
-Michael Ende, Neverending Story
