思想的自由是最珍贵的自由。

我不考虑失败。我考虑下一步。

To be free is to accept responsibility for one's own life.

如果你走在正确的道路上，并且愿意继续走下去，那你总有一天会取得进步。

I came from nothing, so I have nothing to lose.

Society can and does execute its own mandates， and if it issues wrong mandates instead of right， or any mandates at all in things with which it ought not to meddle， it practices a social tyranny more formidable than many kinds of political oppression， since， though not usually upheld by such extreme penalties， it leaves fewer means of escape， penetrating much more deeply into the details of life， and enslaving the soul itself.
