Re: I am PEOPLE PERSON.
I think "people person" has passed into the realm of "trite."
What is it you want to mean when you say it?
I really like meeting new people.
I'm an extrovert and get my energy from being around people.
I think I'm a good listener and people feel comfortable sharing things with me.
(And I agree you don't just say "Hi, I'm Barb. I'm a Gemini, I'm from New York, and I'm a people person!")
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
