Doing the same thing over and over expecting different results. Einstein defined this as insanity.
I define this as...
The holidays.
Trying to create the Pinterest-perfect-Rockwellian holiday, we hurry and worry. We compare and despair. It's as if we've turned the holidays into a competitive sport. Social media being the judge and jury. And the harder we train, and the tougher our game. The worse we feel.
We hold ourselves to the standard of being thin, happy, rich, gracious, grateful, cheerful, merry and bright, while the kids must all get along, and the cards need to be sent on time, and the dog needs to stop eating the ornaments off the tree (or maybe that's just at my house). Which makes us highly susceptible to receiving gifts that we should never accept in the first place.
