永远不要低估一个想法改变世界的力量。
Never underestimate the power of a single idea to transform the world.
过去从未死去。它甚至还没有过去。
没有比不愿看见的人更瞎的了。
I went to the woods because I wanted to live deliberately,I wanted to live deep and suck out all the marrow of life, To put to rout all that was not life, and not when I had come to die, Discover that I had not lived.
我会告诉二十多岁的人不要满足于一份工作、一个职业甚至一个事业。寻找一个使命。即使你不知道那意味着什么，也要寻找它。如果你在追随你的使命，疲劳会更容易忍受，失望会成为燃料，高潮会是你从未感受过的。
Those who dream by day are cognizant of many things which escape those who dream only by night.
The best way to predict your future is to create it.
