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，童年时代的欢乐和悲伤大都成为往事前尘，它们然失去了当时的锋芒；受早期教育过程的那些重大事件，着更加激动人心的伟大发现而被淡忘。

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说，你皆可活两次，顿悟再无来生之时，前尘方逝，今生方始。
