I've never had money to burn, so I'm not sure what having money means. I've been broke before -- enough to beg my family members for money. It didn't make me feel like an introvert though. I don't want power because that always brings responsibility, or at least delegation to those who will be responsible and carry-on.
I always enjoyed being a wall-flower though... Is that an introvert? Not as pretty as some of the girls so I had to acquire a sense of humor. Is that an extrovert? I think that still works for me as an old lady. ;)
It's cool you found a balance that works for you.
