1.	Learn what dilated pupils mean. When your pupils are dilated, it means that you have focused your attention on something and find it interesting; maybe you are looking at an attractive person or even trying to solve a difficult math problem.2.	Learn what constricted pupils mean.When your pupils are constricted, it means you aren’t all that interested in what you are looking at; maybe you are looking at an average-looking person, or the math problem you were trying to solve was too difficult and you have given up.

Learn to identify if someone is interested.

This distinction becomes very important when we realize that attention is not unlimited, and when you go beyond the budget you have, you will fail. This is why you can only do multiple things at once when they are relatively easy and undemanding tasks, such as speaking to a passenger while driving on an empty road. However, you would not attempt to have a conversation while making a turn onto a busy road as you need to focus your attention on driving.

There are two types of thinking, one is fast and the other is slow. Each type of thinking is its own system with individual abilities, limitations, and functions. The main difference between the two is that fast thinking requires little to no effort to operate, whereas a conscious effort is necessary for slow thinking to work. For example, you would use fast thinking to solve the problem “2 + 2 = ?” and slow thinking to fill out a tax form.

The Characters Of The Story

While your two types of thinking often split the labor between themselves well, they can clash when an automatic reaction (fast thinking) comes into conflict with an intention to control it (slow thinking). A universal example of this is trying not to stare at an oddly dressed couple in the same room as you. Sometimes, these clashes are caused by cognitive illusions. An example is experiencing a strong attraction towards someone with a history that forms a negative pattern. The good news is, these illusions can be overcome.
