历史是对于未来最好的老师。历史书中的答案价值万金。

The deeper you go, the more you find yourself.

译文：任凭尘世白日里忙碌得像火一样炽热，我却像云朵飘荡，无忧无虑。

The knowledge that you have emerged wiser and stronger from setbacks means that you are, ever after, secure in your ability to survive. You will never truly know yourself, or the strength of your relationships, until both have been tested by adversity. Such knowledge is a true gift, for all that it is painfully won, and it has been worth more than any qualification I ever earned.
