Okay, I'm game.
Happiness, to me at least, isn't a simple emotion. True, some events can make give a person a brief state of euphoria, but it takes more to make one truly happy. Like the dictionary, I see happiness as contentment with one's life.
Many things help me obtain happiness. Family, talking with friends, playing games, reading a good book, succeeding at a difficult task, and God are all things that make me happy. One alone, however, usually does not provide "happiness." Instead, they just distract me from troubles of everyday life. I need multiple of them to provide lasting pleasure.
Personally, I go through different periods of time where I am happy vs. not as happy. When everything seems to be going right, I'm in a good mood, and there's usually nothing bad happening in my life. If a major catastrophe has occurred, I will be more sullen and/or more emotional in general.
We should strive for happiness, if for the simple reason that it feels good to be happy. Whether it's through robotics, religion, family, friends, or some other way, we should all try to be positive.
Anyway, just my thoughts.
