Every man has a property in his own person. This nobody has a right to, but himself.

Nothing is more precious than independence and freedom.

If you don’t make mistakes, you’re not working on hard enough problems. And that’s a big mistake.

只要是为了一个好的事业，并且有助于美好的生活，每一个风险都值得承担。

"The past is never dead. It's not even past."
