This was a very short visit, but it plunged the little prince into deep dejection.

译文：用钱财交朋友，钱财用完了交情就会断绝；贪美色面结合，到年老色衰时爱情就会消失。

——1963年6月25日在西德市政厅柏林墙前的演说

Sustainability isn't an option - it's our responsibility to the next generation.

Hard work and passion are the keys to success in any field, especially in music.

找出你对某人感觉的最简单方法。说再见。
