实现明天理想的唯一障碍是今天的疑虑。

I find I'm so excited. I can barely sit still or hold a thought in my head. I think it the excitement only a free man can feel, a free man at the start of a long journey whose conclusion is uncertain. I hope I can make it across the border.I hope the Pacific is as blue as it has been in my dreams. I hope to see my friend, and shake his hand. I hope.

智者和愚人都没有害，最危险的倒是智愚参半。
