8. Think of the cup as half full
Optimistic women who expected good things had a 14 percent lower risk of dying from all causes (and 30 percent lower heart disease risk) than pessimists, according to a 2009 University of Pittsburgh study that looked at data from 100,000 women over eight years. Mistrustful, cynically hostile women had a 23 percent higher cancer death rate.
Try this: Be grateful. Instead of dwelling on what didn’t go right, think of three good things that happened today, no matter how small. Write them down. People who keep a gratitude journal feel better about their lives and are more optimistic about the coming week than those who write about their problems or about neutral events, according to research from the University of California, Davis, and the University of Miami.
