［美］曼纽尔•J•史密斯

世界级心理学大师，美国最权威、最负盛名的心理学家，他在加州大学担任心理学教授，同时也是美国心理学会、精神生理学研究协会的会员。

自60年代起，他对“强势”这一革命性的心理自助领域发起研究，并于1975年首次将研究成果集结于本书出版。40余年来，本书多次荣登美国亚马逊图书榜第一名，并先后被英、德、荷、日等几十个国家和中国香港、台湾地区引进版权，全球热销逾千万册。

他以本书内容为基础专门开设的“强势力训练课程”在美国引起巨大轰动，并影响至今。当时前往聆听和学习这门课程的除了哈佛大学、斯坦福大学、加州大学的学生外，还有高盛、摩根大通等世界500强企业员工和美国白宫智囊团、美国FBI以及多个国家的外交人员等。书中的理论和方法，曾被乔布斯、克林顿、希拉里、奥普拉等多位“大人物”亲身实践运用，并立竿见影地改变了他们此后的事业和人生。
