Mind wandering happens when your mind stops being focusing and considers concerns unrelated to what you are doing. Not paying attention has traditionally been viewed as a waste of time, or a lack of discipline, or even an impairment like Attention Deficit Disorder.
But recent psychological studies show that daydreaming or mind wandering improves one's chances of making insights and thinking more creatively about problem solving.Dr. Scott Barry Kaufman, a professor of psychology at New York University says that: "Aha moments don't come from a directed and particular focus on a task, but by letting your mind wander and open up to other possibilities." Almost like a Heisenberg quantum moment where looking at an event finds you locating the key in another way rather than seeing it straight ahead.
Mind wandering rather than focused thought is found to be more effective at problem solving, creativity, planning activities. Even with seeing through the viewpoint of another person. For creative people, mind wandering activities like 'blue sky' method for concept building and 'blue ocean strategizing' allow for thinking to stretch and be productive without stress or the sense of urgency to come up with a plan right there and then.
