Out of curiosity (I think that's sound advice through-and-through): would you say the same thing to the dramatic socialite?
Most of my friends are part of the theatre circle: for a lot of us, impressing people and seeming really cool doesn't come from a desire to be liked, but from the thrill of getting reactions from crowds. It's more the act of people who specialize in trying to handle crowd emotions. Is that a separate thing, or would you bundle that sort of community attitude as attempted impressing?
That's kind of an edge case. But even within acting there's a distinction between actually wowing audiences and trying to seem impressive. The American Repertory Theater in Cambridge is a good example of what not to do.
I hear ya about the debt. Though my dad told me that and I didn't listen as well as I should have, so it might be a waste even coming from myself. I've just now returned to the good credit category.
I mainly mean you should avoid consumption debt-- you should avoid living beyond your means. Debt incurred as part of a project your'e working on could be ok. (Could.)
If you work hard on things you like, you will impress people.
Don't get into debt.
