I enjoyed a drinking time with friends a few days ago. In a talk, a friend suddenly touched on an interesting topic.
He said a person makes a different decision about the same problem if he or she has a different search domain for the problem. That is true. Generally, a good optimizer solves a problem in a given ideal search domain, but it does not find a good result in ill domains. To get good search domains or know new regions, wise people try to learn any. And, the domains can be updated, and most domains are introduced by friends. I believe it is common sense.
Thus, wise men easily cut bad relationships. If a person has a poor man as a friend, the person may have a direction toward the poor. People should cut friends if they are liars, unattractive, or cowardly.
However, most people do not know how to detect them. To the asking, I have an answer. That is drinking beer. If the person likes drinking and no problem happens, he or she is good. Otherwise, he or she has any problems.
This is real.
