This is an old adage that my dad used to say to me when I would stay with him on some weekends. He would have friends over, and they would be doing their own thing, and they used to tell me and my friends that you could stay up later if we stayed “out of sight out of mind.” I’m not sure how I feel about this as a parenting strategy, but it makes a lot of sense when dealing with what you should focus on and what you need to steer clear of from a distraction perspective.
