Out of the best and most productive years of each man's life, he should carve a segment in which he puts his private career aside to serve his community and his country, and thereby serve his children, his neighbours, his fellow men, and the cause of freedom.

  • -- David E. Lilienthal 大卫·E·莉莲塔尔

在每个人一生中最好和最富有成效的岁月里,他应该开辟出一段时间,把他的私人事业放在一边,为他的社区和国家服务,从而为他的孩子、邻居、同胞和自由事业服务。
