The brick walls are there for a reason. The brick walls are not there to keep us out. The brick walls are there to give us a chance to show how badly we want something. Because the brick walls are there to stop the people who don't want it badly enough. They're there to stop the other people.
——Randy Pausch
砖墙在那里是有原因的。砖墙不是要挡住我们。砖墙是给我们一个机会来表明我们是有多迫切地想得到什么东西。因为砖墙是要阻挡那些不诚心的人,以及其他人的。
