not worried
just could be happier
everybody always says, "If I have this, I'll be happy", and when they get it, they are still not happy. Happiness is within you. Bigger muscles, bigger dick, car, etc, they are not gonna make you happy. What you have is a comparison problem---and when you compare yourself to others, you'll either feel superior or inferior, you never are on equal footing.
And nobody wants to be a around a Debbie Downer. Stop focusing on things you have no control over, and focus on things you do have control over---and be happy.
And stop whining like a 12 yr old girl in gym class.
