To succeed, planning alone is insufficient. One must improvise as well.
要成功,仅靠计划是不够的。还必须即兴发挥。
——1964年瑞佛尼亚审判法庭陈述
On the path of science, there are no smooth roads to take; only those who are not afraid of hard work and climb the steep mountain paths have the hope of reaching the glorious summit.
战略不是计划的结果,而是相反:它是计划的起点。
