Adaptability. Life changes far more frequently and more unpredictably than most of us would like. New obstacles range from a closed road on your normal commute to a natural disaster that destroys your home, ranging from the irritating to the devastating. The happiest people in life are . . . the ones who focus on finding the best way around the obstacle. Because they’re adaptable, they don’t have to worry about life’s unpredictability. . . . They simply find another way forward, and proceed.
