One phrase from growing up years we have oft heard and might have even picked up: "It takes only 2 mins. Why not do it right away?"

Context switching is a productivity sniper. It takes about 20 - 30 minutes slide into cognition. Takes only a minute to slide out. One interruption or distraction sets us back by 20 - 30 minutes.

2 mins is never 2 mins. The real cost is the drag on attention.
