In the first year or psychology you learn a lot of words and scientifical language. One of those words you learn is the "homeostasis". Which means the balance between highs and lows and how crucial is for a healthy life. You can study it in basic conditioning (a balance between stimuly, or you can create learned helplessness), in personality (a balance between happyness and depression makes you happier than the happiest person in the world), neuropsychology... and any other field with the same theory behind. So yeah, having balance between everything in your life is the most important thing you can achieve.
Beyond momentary balance, I wonder what the process of looking away and daydreaming for 3 minutes then resuming with an insight will look like once implemented somewhere. There’s some form of benefit. Turning off focused attention, the subconcious steals the ball and entertains the primary attention with a little unrelated circus, then passes back the ball with something new to the focused attention.
