——1912年在旧金山丽蝉戏院的演说

聪明的投资是价值投资，获得的比你付出的更多。

You do not need to leave your room. Remain sitting at your table and listen. Do not even listen, simply wait. Do not even wait, be quite still and solitary. The world will freely offer itself to you to be unmasked, it has no choice, it will roll in ecstasy at your feet.

出自先秦《荀子·不苟》。君子加强道德修养没有比“诚”更重要的，达到了“诚”的要求也就到了修身养性的最高境界了。

心理学家必须是一个中立的观察者。
