影响合理决策的两个最大的障碍是你的自我意识障碍和思维盲点障碍。这两个障碍使你难以客观地看到你和你所处环境的真相，难以最大限度地利用他人的帮助来做出最佳决策。如果你能理解人类大脑这部“机器”是如何运行的，就能明白这两个障碍为何存在，以及如何改变你的行为，从而让你自己更快乐、更高效、更擅长和他人交流。
The two biggest barriers to good decision making are your ego and your blind spots. Together, they make it difficult for you to objectively see what is true about you and your circumstances and to make the best possible decisions by getting the most out of others. If you can understand how the machine that is the human brain works, you can understand why these barriers exist and how to adjust your behavior to make yourself happier, more effective, and better at interacting with others.
