The notion of “flow”, also known colloquially as being “in the zone”, is a state where one just breezes through the task at hand and one is fully focused on the task as subjective time distorts. Part of sports psychology deals with training athletes to get into the zone. One thing that athletes are told to do is ignore the manual details of the sport and focus on their goals. For example, professional golfers perform better when they focus on putting that little white ball in the cup and ignore their swing.
Mental illnesses are “real” and not just a state of mind that most people can just “get over”. Drug companies invent mental illnesses to sell more drugs. I believed and do believe both these things at the same time. Am I guilty of doublethink? I certainly thought so when I first realized I held them.
