Lucky people tend to listen to their intuition, which helps them to avoid bad situations and maximize good opportunities. If you have a feeling that you'll win a writing contest, for example, don't let your brain talk you out of entering. It's all too easy to say, "Oh, I'm not good enough to win" despite your intuition telling you that there's a great entry just waiting to be written!
Intuition helps lucky people outside of sweepstakes as well. How many of us have gotten involved in a bad relationship, even though there were warning bells going off in our heads?
