Perception.

Life is not that serious, yo! I feel like these people in NYC are all so hardened, rough to the world. It's,umm...interesting.

But for real, have you ever noticed how some people just seem to have that glow about them, always seeming happy, upbeat, together, etc...while others don't? I think people lose sight of the fact that those glowing people, they have the same issues and insecurities that everyone else has. They just know how to mask it, or just learn to accept it, put it aside, and look forward. It's really up to you what kind of person you want to be. Or come across as.
