心理学关注心理生活的“是什么”和“怎么样”，而非“为什么”。
Psychology is concerned with the what and how of mental life, not the why.
The only limit is your mind.
You can't let praise or criticism get to you. It's a weakness to get caught up in either one.
I don't do things for the reaction or the credit. I do things because they're what I want to do.
恐惧无时无刻地在我们耳边窃窃私语、在我们眼前高声呐喊；而信念必须由你们每天在镜中看到的自己培养。前者总是紧追在我们身后、纠缠不休、令我们停滞不前；后者则激励我们、带给我们惊喜、刺激我们的创造力、驱使我们不断地前进。
意识的存在是为了行动。
Power is not just about what you can do, but what you can make others do.
