If you are already an introvert, developing the skills to be an extrovert will let you have the choice & flexibility to jump between the two whenever you want to. There's nothing wrong with feeling comfortable being alone (indeed that's a good skill to have, and not everyone has that). But there may come a time when you would like to be more extroverted occasionally & make more friends. If you don't build that skill now, you'll find it more difficult to be extroverted at the times when you need it.
