心理活动的目的是成功的生活。
如果你的梦想没有吓到你，那它们就太小了。
——1963年6月25日在西德市政厅柏林墙前的演说
Those who can endure the worst blows of fate are often the strongest individuals.
The things we admire in men, kindness and generosity, openness, honesty, understanding and feeling, are the concomitants of failure in our system. And those traits we detest, sharpness, greed, acquisitiveness, meanness, egotism and self-interest, are the traits of success.
