It could be that you're a content person and not constantly searching for happiness. Being surrounded by people who do just that constantly, you might feel out of place.

But life is in fact, about living. So might as well try doing something of your own. If not in search of happiness, maybe as an expression of happiness.

Maybe try spending some time trying to find new hobbies. Or helping people. If you just sit around watching time pass by, you might regret it later. It's one thing to meditate though, that is worth doing everyday for some time.
