I will persist until I succeed.

坚持不懈，直到成功。

I will never consider defeat and I will remove from my vocabulary such words and phrases as quit, cannot, unable, impossible, out of the question, improbable, failure, unworkable, hopeless, and retreat; for they are the words of fools. I will avoid despair but if this disease of the mind should infect me then I will work on in despair. I will toil and I will endure. I will ignore the obstacles at my feet and keep mine eyes on the goals above my head, for I know that where dry desert ends, green grass grows.

我绝不考虑失败，我的字典里不再有放弃，不可能、办不到、没法子、成问题、失败，行不通、没希望、退缩…这类愚蠢的字眼。我要尽量避免绝望，一旦受到它的威胁，立即想方设法向它挑战。我要辛勤耕耘，忍受苦楚。我放眼未来，勇往直前，不再理会脚下的障碍。我坚信，沙漠尽头必是绿洲。
