korien_jan29It’s hard to quantify a person’s personality scientifically, but one factor that is relatively easy to measure is introversion vs extroversion. We think of an extrovert as someone who enjoys being with other people and an introvert as someone who is shy and likes to be alone, often spending most of their time reading or studying. However, there are extroverts who enjoy reading and introverts who enjoy partying with friends or performing on stage. The difference is that extroverts receive energy from being around others, while introverts find it uses up energy and they need alone time to recharge.
