I'd heard about a ratio of 3:1, when coping with negativity, from the research of John Gottman. If someone, he found through research, had a negative thought, it would take 3 positives to counter it. With teams, it's 5 to one.
Today it happened at the doctor's office, where I needed a new prescription for my worn orthotics. The secretary was dismissive, not looking into my eyes, and just ignoring me. Later, I felt awful.
So I played 3 inspirational songs: I'm a survivor(Destiny's Child); Fighter(Christina Aguilera) and What a Man(Salt n Pepa).
