没有魔法，就没有艺术。没有艺术，就没有理想主义。没有理想主义，就没有正直。没有正直，除了生产什么都没有。

"I hope that in this year to come, you make mistakes. Because if you are making mistakes, then you are making new things, trying new things, learning, living, pushing yourself, changing yourself, changing your world. You're doing things you've never done before, and more importantly, you're doing something."
