Barbara Fredrickson, a noted psychology researcher at the University of North Carolina, Chapel Hill, recommends a 3:1 balance of positive and negative emotions, based upon mathematical modeling of ideal team dynamics by her collaborator Marcial Losada, and confirmed by research on individual flourishing and successful marriages. (Calculate your “positivity ratio” at www.positivityratio.com).3:1 makes intuitive sense, but mathematical model? Label me "unconvinced".
The second advice seems more practical:
Apply the brakes.Your brain continuously scans your internal and external environment, even when you are focused on a particular task. Distractions are always lurking: wayward thoughts, emotions, sounds, or interruptions. Fortunately, the brain is designed to instantly stop a random thought, an unnecessary action, and even an instinctive emotion from derailing you and getting you off track.
What can you do? To prevent distractions from hijacking your focus, use the ABC method as your brain’s brake pedal. Become Aware of your options: you can stop what you are doing and address the distraction, or you can let it go. Breathe deeply and consider your options. Then Choosethoughtfully: Stop? or Go?
