Besides, many of the joys and sorrows of childhood have lost their poignancy; and many incidents of vital importance in my early education have been forgotten in the excitement of great discoveries.

此外，童年时代欢乐和悲伤大都成为往事前尘，它们已然失去了当时锋芒；在我接受早期教育过程那些重大事件，已经随着更加激动人心伟大发现而被淡忘。

As the ancient philosopher Confucius once said, we have two lives and the second begins when we realize we only have one.

正如古代哲人孔子所，我皆可两次，顿悟再无来之时，前尘方逝，今方始。
