不慎重的话语会导致苦难，而温和的言语能带来和平。

——在柏林墙演说

What we know is not much. What we do not know is immense.

I write fiction and I'm told it's autobiography, I write autobiography and I'm told it's fiction, so since I'm so dim and they're so smart, let them decide what it is or it isn't.

There will be obstacles. There will be doubters. There will be mistakes. But with hard work, there are no limits.
