In today's world, everyone faces problems; professional, personal, or psychological. Not only individuals, organizations and governments face problems. It is easier to escape from a problem than face it. But simple or complex, problems need to be solved within a timeframe so that goals are achieved. Problem-solving can be both a science and an art. There are many well-defined approaches to solving mathematical, scientific or engineering problems. Psychologists approach to problem-solving in many ways. According to the situations and their emotional and intellectual capabilities, people adopt different techniques and strategies to solve the problems. Norman Vincent Peale, the famous American author, known for popularizing the concept of positive thinking has rightly said, "Problems are to the mind what exercise is to the muscles, they toughen and make the mind strong."
