Preschool kids ask their parents an average of 100 questions a day. By middle school, they’ve basically stopped asking questions. Curiosity is a lost superpower.
As children, people would tell us we could either view the glass as half-full or half-empty. This point of view would then define how we look at life. Are you an optimist or a pessimist? Just think of that half-filled (or half-empty) beverage and you have your answer. We use these terms to then define ourselves and others in these simple terms. In 1990, however, Martin Seligman proved that optimism can be learned—by anybody at any age. Pessimists couldn’t believe it! Peter Schulman then demonstrated that optimists sold 35% more than pessimists. Optimism suddenly became a trait worth hiring for in sales.
