what industries don't require a silver tongue?

title. ive never been a charming person, I don't really build rapport naturally very well. maybe it's something you can get better but a lot of people also say you have to be a natural. what sales industries are the best for people like this? I know that car sales is an industry where you basically have to have that kind of extroverted personality, which is why I'd never step into that area. I'm wondering for the introverted folks here what industries have you seen success in?
