You can pretty much convince me to do just about anything by citing research that proves how effective the thing is. I'm not going to be swayed, however, by a hokey plot that involves a fictional woman who is universally considered to be the best mother. Equally unpersuasive are her fictional daughters--each one a supermom in her own right--who are mysteriously unwilling to dole out more than one piece of wisdom at a time.
In this magical, mythical family, the women have tons of free time because they have mastered the art of one-minute motherhood. The strategy includes writing down family and individual goals with your kids (and revisiting those goals regularly to assess progress), noticing when kids so something right and praising them for it, and delivering the heavily scripted one-minute reprimand (which includes stating what the kids did wrong, acting as angry as you can to show how mad it's made you, pausing for a moment of silence, and then touching the kids and reassuring them that they are good people and you still love them).
In spite of the author's cheesy attempt to turn his bullet points into a narrative, the advice here seems reasonable and worth a try.
