Psychology studies have found that whether you identify yourself as lucky or unlucky, regardless of your actual lot in life, says a lot about your worldview, well-being, and even brain functions. It turns out that believing you are lucky is a kind of magical thinking—not magical in the sense of Lady Luck or leprechauns. A belief in luck can lead to a virtuous cycle of thought and action. Belief in good luck goes hand in hand with feelings of control, optimism, and low anxiety. If you believe you’re lucky and show up for a date feeling confident, relaxed, and positive, you’ll be more attractive to your date.

In American schools, bullying is like the dark cousin to prom, student elections, or football practice: Maybe you weren’t involved, but you knew that someone, somewhere was. Five years ago, President Obama spoke against this inevitability at the White House Conference on Bullying Prevention. “With big ears and the name that I have, I wasn’t immune. I didn’t emerge unscathed,” he said. “But because it’s something that happens a lot, and it’s something that’s always been around, sometimes we’ve turned a blind eye to the problem.”

We know that we shouldn’t turn a blind eye: Research shows that bullying is corrosive to children’s mental health and well-being, with consequences ranging from trouble sleeping and skipping school to psychiatric problems, such as depression or psychosis, self-harm, and suicide.
