"The only limit to our realization of tomorrow is our doubts of today."
实现明天的唯一限制是我们今天的疑虑。
The habit of committing far more time to learning and thinking than to doing is no accident.
The right of nature... is the liberty each man hath, to use his own power, as he will himself, for the preservation of his own nature; that is to say, of his own life.
过去从未死去，它甚至还未过去。
