The world loves extroverts. These people are chatty, gregarious, always have stories to tell, and seem to get along so easily.
Introverts on the other hand, seem to struggle to get along with most, and prefer to be curled up with a book rather than the centre of attention in a pub.
A book called Quiet by Susain Cain explores how introverts are actually very powerful, can think deeply and make massive contributions to the world in their own ways.
But maybe extroverts and introverts as defined by outward behaviour is irrelevant, even though that is what catches the eye. Dig a little deeper, and what may really matter is empathy.
One can make quick and superficial judgements about people looking at how they behave in public (intro or extro). But when someone goes the extra mile, out of the way to do something for someone else, that is the true basis for a sustainable relationship. In this respect, even an introvert could be an extrovert, by thinking about the other person selflessly.
