Less that, and more... you may have a vision of who you are, yourself. But the way others see you is based on how you act, and that's who you are to them. It doesn't matter who you think you are if your actions don't reflect that. You can't be a jerk and say "but I'm nice on the inside", people will just think you're a jerk because that's how you act.

If you think abstractly, it's about following the consensus to blend in... but questions about the true self and who you really are are the questions I hear more often. More than questions of reality, that is.
