well introverts n many cases can turn extroverts with training & time & usually with the help of a psychologist & usually those cases needs that change for their work like politicians/ singers/ actress/ athletes/ managers, n most cases being an introvert doesn't negatively affect one's life because it's not that he/she doesn't talk but rather it's being much more selective whom to talk to & there's absolutely nothing wrong with that, so the only case to worry about is the rare case that "literally talks to no one" for months or even years!. have a good day
