Just because something seems to make other people happy doesn't mean that it really does. People are very good at pretending they're happy, especially when they've invested so much into the things that are supposed to make them happy; it's hard to admit that you've been placing all your eggs in the wrong basket.

Happy people are not happy all the time. Everyone has times when they feel sad, frustrated, guilty, angry and so on. Happy people are just better at bouncing back to a state of contentedness. We may all feel negative at some moment in our lives, but try to bounce back and live in the moment, and be content with everything you do.
