The only limit to our realization of tomorrow will be our doubts of today.
我们实现明天的唯一限制将是我们今天的疑虑。
没有自由就没有创造,没有创造就没有真正的生活。
The only way to deal with an unfree world is to become so absolutely free that your very existence is an act of rebellion.
For the eyes of the world now look into space, to the moon and to the planets beyond, and we have vowed that we shall not see it governed by a hostile flag of conquest, but by a banner of freedom and peace.
Freedom is nothing but a chance to be better.
【大意】古来圣哲不珍视直径成尺的璧玉,却珍重每一寸光阴,因为时间最是难得,却最容易失去。
You don't have to be perfect to inspire others.
