You don't have a 'right' to happiness, because that's not something you're entitled to. That's something you earn, and some people never find it. Plus, happiness is a state of mind; it's not a constant or destination after a journey. I'd even go as far as to say that the average person isn't 'happy', just 'surviving'. Like others have said here, happiness comes from you. If you're not happy, look at your life objectively. If you have a string of consistent bad luck or incidents, then the most common denominator is you.
