Set aside 10 minutes before you go to bed each night to write down three things that went really well that day. Next to each event answer the question, “Why did this good thing happen?”
Instead of focusing on life’s lows, which can increase the likelihood of depression, the exercise “turns your attention to the good things in life, so it changes what you attend to,” Dr. Martin E.P. Seligman said. “Consciousness is like your tongue: It swirls around in the mouth looking for a cavity, and when it finds it, you focus on it. Imagine if your tongue went looking for a beautiful, healthy tooth.” Polish it.
