All of these dimensions have implications for our well-being, for how our life goes. And so we know that, for example, openness and conscientiousness are very good predictors of life success, but the open people achieve that success through being audacious and, occasionally, odd. The conscientious people achieve it through sticking to deadlines, to persevering, as well as having some passion. Extroversion and agreeableness are both conducive to working well with people. Extroverts, for example, I find intriguing. With my classes, I sometimes give them a basic fact that might be revealing with respect to their personality: I tell them that it is virtually impossible for adults to lick the outside of their own elbow.
