And it can be harmful. People use their categorization as an excuse (I know I have). "I'm an INTP, I can't have a normal career, I always lose interest and move on to the next thing!" Yeah... this is called being undisciplined. Experts and Masters aren't born with the discipline to master their craft. They struggle like anyone else, but they break through those barriers and continue their mastery. Don't use your personality as an excuse to get around the discipline and practice components of success. Don't let the introvert label be an excuse for you being a standoffish asshole or a hermit. Go on the subreddits for these ... such as /r/INTP and browse a bit ... they are sad.
