There are two ways to live. As an anticipater and as a reactor. Now I know that that doesn’t break down humans completely, there are many more areas of life that we fall down into. However these two are very important to determining what type of person we are. Which one is better is a matter of opinion, which one you are is a matter of character. The one thing that is constant is reality.
Another important piece to understanding people is understanding how they react and how they anticipate. The former is easy once you understand what to look for while the latter is very hard to see and might require thought specific to the situation. Always remember that to understands a persons’ mind is to have the ability to understand and even predict their actions. To do that is control.
Furthermore on the topic of control, there are certain ways in which you can sort out what will help you control someone and what won’t. First remember that everyone is different and everyone is the same. By this I mean that everyone clings onto different things, everyone appeals to different emotions, everyone has different experiences/histories. However, everyone has the same set of reasons, by abusing this fact we can gain trust and with that the answers to the specifics of what makes them different. Then the variable is accounted for and you can solve the equation.
