How important is it that your job matches your personality? Extremely.

Your personality will partially determine how good you are at your job, especially if you have a complex job that requires more than rote behavior. So are you and your job a good fit? If you're a creative person who is open to trying new things—openness being one of the Big Five personality traits—you're more likely to succeed at jobs that require novel solutions over efficient ones. On the other hand, if you're conscientious—another Big Five personality trait—you're likely to be better off in a management or administrative position.
