008-懒惰的大脑
The workings of mind are described as an uneasy interaction between two fictitious characters: the automatic system1 (subconsciousness) and effortful system 2(consciousness). One of the main functions of System 2 is to monitor thoughts and actions " suggested" by system 1.
System 1 is indeed the origin of things we did wrong and also it's the things we did right. Our thoughts and actions are routinely guided by system 1 and generally are on the mark.
System 2 has a overload problem and tend to be very laze due to the law of least effort. System 2 will think as less as possible. This is why some people tend to have less mental power than others, because laziness is the nature of System 2, if you are not intentionally to use cognitive effort, then most likely you would not use your System 2 to think problems.This is something that needs practice along the way.
 If people who are simultaneously challenged by cognitive task and by temptations are most like to yield to the temptation. Because system 1 is in control of behaviors when System 2 is loaded with tasks and is busy. I tends to say the first thing that comes into my mind. I also has trouble delaying gratification, this is a sign of weak System 2.
Both self-control and cognitive effort are forms of metal work. Too much concern about how well one is doing over a task sometimes disrupts by loading too much pointless anxious thoughts. self-control requires metal effort that is something System 2 performs.
A happy mood loosens the control of system 2 over performance: when in good mood, people become more intuitive and more creative but also less vigilant and more prone to logical errors. Therefore, if you are in a good mood today, you should remind yourself of that your System 2 is weaker than usual. you should be extra careful.
