"Freedom is a pretty strange thing. Once you've experienced it, it remains in your heart, and no one can take it away. Then, as an individual, you can be more powerful than a whole country.

I think I'm an eternal optimist. I think optimism is whether you are still exhilarated by life, whether you are curious, whether you still believe there is possibility. From this perspective, I am very much an optimist."
