Be audacious. There is always a best possible path. Your job is to find it and have the courage to follow it. What you think is attainable is just a function of what you know at the moment. Once you start your pursuit you will learn a lot, especially if you triangulate with others; paths you never saw before will emerge. Of course there are some impossibilities or near-impossibilities, such as playing center on a professional basketball team if you’re short, or running a four-minute mile at age seventy.
大胆一些。总有一条最佳路径。你的工作就是找到它并有勇气遵循它。你认为可以实现的只是你目前所知道的函数。一旦你开始你的追求，你会学到很多东西，特别是当你与他人进行三角测量时；你以前从未见过的道路将会出现。当然，也有一些不可能或近乎不可能的事情，比如如果你身材矮小，就可以在职业篮球队打中锋，或者在七十岁的时候跑四分钟一英里。
