The ideal of behaviorism is to eliminate coercion: to apply controls by changing the environment in such a way as to reinforce the kind of behavior that benefits everyone.

The only constant in life is change.

最重要的是保持真实。

当你想要放弃的那一刻，想想你为什么坚持了这么久。

马跑不起来都是因为太瘦；人不能扬眉吐气就是因为贫穷。

人类的心灵和自然界之间存在密切的联系，我们的情感与外在世界相互交织。

仅仅做好事是不够的；必须以正确的方式去做。
