Impossible is just a big word thrown around by small men who find it easier to live in the world they've been given than to explore the power they have to change it. Impossible is not a fact. It's an opinion. Impossible is not a declaration. It's a dare. Impossible is potential. Impossible is temporary. Impossible is nothing.

“不可能”只是弱小者的夸大其词，他们发现在既定世界中得过且过要比探索改变的力量来的安逸。不可能并非事实，而是看法；并非宣言，而是挑战。不可能是一种潜力，是暂时的，没有什么是不可能的。
