Curiosity didn't kill the cat; it saved the marriage. Curiosity is the single most important trait in finding a good date or life-partner, writes psychologist Paul Dobransky. "For many busy people with heavy workloads, duties, and stress, it might not occur at first that there are good and bad investments we make - even in the very first moments of spending time, energy, or any resources on a potential date, mate, or eventual spouse. If we could only choose one thing to look for, it ought to be their capacity for curiosity."
