I want you to know， it isn’t always clear in the beginning because as I said I had been on television since I was 19 years old. But around ’94 I got really clear. So don’t expect the clarity to come all at once， to know your purpose right away.

The most important thing in science is not to stop questioning.

I'm stronger than I thought.

让我告诉你引导我达到目标的秘密。我的力量仅在于我的坚韧。
