Have you heard about the purple bracelet people?

"Begin to wear the bracelet, on either wrist.

When you catch yourself complaining, gossiping or criticizing (it’s ok, everyone does) move the bracelet to the other arm and begin again.

If you hear someone else who is wearing a bracelet complain, you may point out their need to switch the bracelet to the other arm; BUT if you’re going to do this, you must move your bracelet first!

Stay with it. It may take many months but when you reach 21 days you will find that your entire life is happier, more loving and more enjoyable."

“Complaining is not to be confused with informing someone of a mistake or deficiency so that it can be put right. And to refrain from complaining doesn’t necessarily mean putting up with bad quality or behavior. There is no ego in telling the waiter your soup is cold and needs to be heated up—if you stick to the facts, which are always neutral. ‘How dare you serve me cold soup…?’ That’s complaining.”

—Eckhart Tolle, “A New Earth”
