译文：月亮过了十五后，就逐渐不明亮了，人到了中年之后，做什么事都难以有大作为。赏析：青少年是人生最美好的时期，这个时期精力最旺盛，记忆力最强，也是人生最该努力奋斗的时候。

I have made all the calculations; fate will do the rest.

"The best and most beautiful things in the world cannot be seen or even touched - they must be felt with the heart."

I don’t complain, I don’t make excuses, I just keep going.

Mental processes exist because they have served life's continuance.
