"introverts prefer to work independently, and solitude can be a catalyst to innovation. As the influential psychologist Hans Eysenck once observed, introversion "concentrates the mind on the tasks in hand, and prevents the dissipation of energy on social and sexual matters unrelated to work." In other words, if you're in the backyard sitting under a tree while everyone else is clinking glasses on the patio, you're more likely to have an apple fall on your head."
