Introversion is awesome as a career tool. As an introvert your low tolerance for dopamine makes it easier for you to stay focused for long periods of time. It makes it easy for you to really feel a high level of engagement in complex and creative tasks where you have to look inwards. At this point in my career id say that introversion is my super power. I trust my ability to reflect and analyze. I trust myself with the notion that any task I get, I can solve when I get to ponder it on my own, behind a closed door.
