不沉溺于过去,专注未来。
                    写作是唯一一个不赚钱也不会被人嘲笑的职业。
                    理解复杂系统的行为需要一种新的思维方式,一种接受不确定性和不可预测性的思维方式。
                    行为由驱力和习惯强度的相互作用决定。
                    It is better to be a human being dissatisfied than a pig satisfied; better to be Socrates dissatisfied than a fool satisfied.
                    I always try to be positive, even in difficult moments.
