A failure is not always a mistake, it may simply be the best one can do under the circumstances. The real mistake is to stop trying.
失败并不总是错误，它可能只是一个人在特定情况下能做到的最好结果。真正的错误是停止尝试。
死亡并不存在，人们只有在被遗忘时才会死去；如果你能记住我，我将永远与你同在。

In the search for truth, there are no final answers, only better questions.
永远追求卓越，而不是完美。
不是所有面对的事情都能改变，但在面对之前，什么都不会改变。
