Here's one of my favorite Seinfeld scenes. George Costanza, the long-suffering character with his long string of bad luck, concluded that his life has been the complete opposite of how he had wanted it to be. He decided to counter that by doing the opposite, starting from foregoing his usual order at the Diner.
Though the situation is highly exaggerated (since it's a show afterall), it can serve as a good reminder: If what you've been doing hasn't been working out for you, do a George. Do the opposite, and you might find yourself a little surprise there.
