实现明天的唯一限制是我们今天的疑虑。
The only limit to our realization of tomorrow is our doubts of today.
聪明的投资者是现实主义者，他们向乐观主义者出售，从悲观主义者那里购买。
The man who believes that the secrets of the world are forever hidden lives in mystery and fear. Superstition will drag him down. The rain will erode the deeds of his life. But that man who sets himself the task of singling out the thread of order from the tapestry will by the decision alone have taken charge of the world and it is only by such taking charge that he will effect a way to dictate the terms of his own fate.
沾沾自喜时，应该约束反省；怒不可遏时，应该约束反省；怠倦懒惰时，应该约束反省；思想狂放时，应该省约束反。
Quality is not an act, it's a habit.
最终，我们记住的不是敌人的话语，而是朋友的沉默。
