哪位英语高手可以告诉我这句名言的英语原文,非常感谢

楼上的是自己译的?
原文如下：You are as young as your faith,as old as your doubt; as young as your self-confidence,as old as your fear,as young as your hope,as old as your despair.When the wires are all down and all the innermost core of your heart is covered with the snows of pessimism and the ice of cynicism,then you are grown old indeed.But so long as your heart receives messages of beauty,cheer,courage,grandeur and power from the earth,from man and from the Infinite,so long you are young.

You have faith on the young, the old suspicions; confidence on the young, the elderly fear, there is hope on the young, despair on the elderly; years so that your skin wrinkling, but lost enthusiasm, the soul of the injury. -- Carnegie
