People will get stupid (really getting stupid) because they spend time and attention on meaningless things while we know that nowadays focus, time, and attention is the most important resource. I repeat again "focus", "time", and "attention" is the most important resource, the time when everything is available (information) then determining the focus on a goal is the most important key to success. Because the focus not only says "yes" to 1 thing, but also says "no" to thousands of other alternatives.
